49ers key matchup No. 2: Aldon Smith vs. Martin

This is the second part in a series that spotlights three 49ers-Dolphins matchups to watch Sunday, 1 p.m. (CBS), at Candlestick Park.

49ers ROLB Aldon Smith vs. Dolphins LT Jonathan Martin

Tale of the tape
Smith (99): 6-foot-4, 258 pounds, second season, Missouri
Martin (71): 6-foot-5, 312 pounds, rookie, Stanford

Aldon Smith is closing in on Michael Strahan's NFL record of 22.5 sacks in a single season. With a league-leading 17.5 sacks, Smith needs five sacks in the final four games to get there.

Smith figures to be a focus each week. And on Sunday, he appears to have a significant advantage as he goes against Miami Dolphins rookie Jonathan Martin, who makes his first start on the left side after starting at right tackle up to this point.

Martin, whom the Dolphins selected in the second round of the draft, was originally projected as a mid-first-round selection. But his stock took a hit when he hoisted 225 pounds on the bench press just 20 times at the NFL scouting combine.

Martin played for 49ers coach Jim Harbaugh during his college career at Stanford.

"He was a good player for us at Stanford," Harbaugh said. "He's been doing a good job his entire rookie year, and to make the switch from right tackle to left tackle, he's adapted and doing a good job. With losing their left tackle, he'll be called on this week."

Martin takes over at left tackle after Dolphins All-Pro Jake Long was placed on injured reserve with a season-ending torn triceps. Defensive tackle Justin Smith described Martin this week as a "serviceable tackle in this league."

Martin will need to muster every bit of strength, as well as quickness, to keep up with Aldon Smith, who has demonstrated a wide array of moves as an every-down outside linebacker in his second NFL season. Smith already has recorded more sacks in his first two seasons than any other pass-rusher since the NFL began tabulating sacks in 1982.

"Some guys can get close but not finish," 49ers defensive coordinator Vic Fangio said. "Those guys can get close and finish. It takes a special skill set. You've got to have something special, one way or another, either one thing or two things. In Aldon's case, he's got length. He's got slipperiness. He's got some strength."

Taking a closer look at Ryan's criticism of Shanahan

Taking a closer look at Ryan's criticism of Shanahan

There is no shortage of blame to go around for the Atlanta Falcons’ collapse in Super Bowl 51.

The Falcons built a 28-3 lead in the middle of the third quarter and let it slip away, ultimately falling to the New England Patriots, 34-28, in overtime.

Matt Ryan voiced one previously undisclosed factor in the collapse this week in an interview with Pete Prisco of CBS Sports, pointing the finger at the new coach of the 49ers.

Kyle Shanahan has been the focus of a lot of the blame, but critique from the league MVP was a new one.

The Falcons quarterback faulted his former offensive coordinator for taking too much time to relay the play calls. Ryan said he did not have enough time to change any of the plays – presumably checking out of called pass plays to run the ball.

Here’s what Ryan told Prisco:

"Kyle's play calls -- he would take time to get stuff in. As I was getting it, you're looking at the clock and you're talking 16 seconds before it cuts out. You don't have a lot of time to say, 'There's 16 seconds, no, no, no, we're not going to do that. Hey, guys, we're going to line up and run this.' You're talking about breaking the huddle at seven seconds if you do something along the lines.

"With the way Kyle's system was set up, he took more time to call plays and we shift and motion a lot more than we did with (former coordinator) Dirk (Koetter). You couldn't get out of stuff like that. We talk about being the most aggressive team in football. And I'm all for it. But there's also winning time. You're not being aggressive not running it there."

The 49ers can point to mismanagement of the clock for their own Super Bowl heartbreak. The 49ers’ offense had the perfect play call at the perfect time against the Baltimore Ravens late in Super Bowl XLVII.

But with the play clock striking :00, coach Jim Harbaugh was forced to call a timeout from the sideline. A split-second later, the ball was snapped and it appeared the quarterback run would have easily ended up with Colin Kaepernick in the end zone.

Much like after the 49ers’ loss, the Falcons left plenty of room for second-guessing.

Two of Shanahan’s plays calls, which directly led to the collapse, will forever be scrutinized.

The first came with 8:31 remaining in regulation and the Falcons holding a 28-12 lead. On third and 1 from the Atlanta 36, Shanahan did not remain conservative with an expected run play. He swung for the fence.

Receiver Aldrick Robinson, whom the 49ers added this offseason as a free-agent pickup, was breaking free past the Patriots secondary for what could have been a touchdown. But just as Ryan was unloading, New England linebacker Dont’a Hightower hit him and forced the fumble. Running back Devonta Freeman whiffed on blitz pickup, which would have provided Ryan with enough time to target Robinson deep.

Ryan’s explanation does not appear applicable on this play, though. In watching the replay, the Falcons broke the huddle with more than 25 seconds remaining on the play clock and the snap occurred with :15 to spare.

The other questionable sequence came after the Falcons – leading by eight points -- got to the New England 22-yard line with less than five minutes to play. The Falcons lost 1 yard on a run play on first down.

On second down, Ryan was sacked for a 12-yard loss. Before that play, the Falcons broke the huddle with :19 on the play clock. The snap occurred with :04 remaining. The game clock was running, so the Falcons had reason to attempt to burn as much clock as possible.

In the fourth quarter, the Falcons never seemed rushed to get off a play. The closest they came to delay-of-game penalties were when they snapped the ball with :04 on the one play and :03 another time. The majority of their snaps occurred with :10 or more seconds to spare.

If the Falcons were guilty of anything when it came to the play clock, it was that the offense did not waste more time. After New England pulled to within 28-9 late in the third quarter, the Falcons ran only six offensive plays while the game clock was running.

On those six plays, the Falcons snapped the ball with :13, :09, :14, :20, :13 and :04 remaining on the play clock. If they’d snapped the ball with one second remaining each time, they could have shortened the game by 1 minute, 7 seconds. The Patriots scored the game-tying touchdown with :57 remaining in regulation.

Uh-oh: Is Kyle Shanahan going to be Harbaugh-tastic in his timing?

Uh-oh: Is Kyle Shanahan going to be Harbaugh-tastic in his timing?

Until now, Kyle Shanahan’s hiring by the San Fracisco 49ers looked great because of his two-and-a-half predecessors – the last days of Jim Harbaugh, the misplaced concept of Jim Tomsula and the couldn’t-make-chicken-marsala-out-of-old-Kleenex problems surrounding Chip Kelly.

But now, Atlanta Falcons quarterback Matt Ryan has told us all that Shanahan has a gift we in the Bay Area know all too well. Specifically, that Shanahan took too long to call plays to the Super Bowl the Falcons vomited up to the New England Patriots.

Now who does that remind you of, over and over again?

Yes, some things are evergreen, and too many options in this overly technological age seems to be one of them. Data in is helpful, but command going out is what bells the cow. Ryan said Shanahan was, well, almost Harbaugh-tastic in his timing.

“Kyle’s play calls -- he would take time to get stuff in,” Ryan told Bleacher Report. “As I was getting it, you're looking at the clock and you’re talking 16 seconds before it cuts out. You don't have a lot of time to say, ‘There's 16 seconds, no, no, no, we're not going to do that. Hey, guys, we're going to line up and run this.’ You're talking about breaking the huddle at seven seconds if you do something along the lines.

“With the way Kyle's system was set up, he took more time to call plays and we shift and motion a lot more than we did with (former coordinator) Dirk (Koetter). You couldn't get out of stuff like that. We talk about being the most aggressive team in football. And I'm all for it. But there's also winning time. You’re not being aggressive not running it there.”

And the reason this matters is because the Atlanta Shanahan had multiple good options on every play. In San Francsco, at least in the short term, he’ll be dealing with minimal options. That could speed up his choices, as in “What the hell, we don’t have Julio Jones.” But it could also mean more delays, as in, “Okay, him . . . no, maybe not . . . no, he just screwed up that play last series . . . oh, damn it, time out!”

In short, it’s growing pains season here, children. On the field, on the sidelines, and maybe even in Kyle Shanahan’s head.
