Editor's note: 49ers Insider Matt Maiocco breaks down the first round of Thursday's NFL Draft the way he sees it playing out. Check out our NFL Draft central for comprehensive draft analysis.
1 Kansas City: OT Luke Joeckel, Texas A&M -- Left tackle Branden Albert appears to be on the move, so Alex Smith gets a rookie to protect his blind side.
2 Jacksonville: OT Eric Fisher, Central Michigan -- They need help on the offensive line, and it's difficult to separate Joeckel and Fisher. In whatever order, they'll fly off the board.
3 Oakland: OT Lane Johnson, Oklahoma -- Yes, I realize a 40 time for an offensive lineman is no longer a big deal around Raiderland. But Johnson is the next-safest choice.
4 Philadelphia: DT Sharrif Floyd, Florida -- While ex-Oregon coach Chip Kelly might be tempted to go with Dion Jordan, the Eagles take Floyd after the Raiders unexpectedly pass him up.
5 Detroit: DE Dion Jordan, Oregon -- After losing Cliff Avril to the Seattle Seahawks, Jordan comes on to provide the Lions with some pass rush.
6 Cleveland: CB Dee Milliner, Alabama -- Nick Saban's players go to the NFL with a laundry list of injuries because of the physical demands he places on them. But there's nothing in the medical report that scares the Browns from this long-term investment.
7 Arizona: OG Chance Warmack, Alabama -- With the addition of Carson Palmer, it's imperative the Cardinals do something to upgrade their offensive line.
8 Buffalo: QB Ryan Nassib, Syracuse -- I'll go on the record as saying I don't like this pick. That said, I believe the Bills want to pair new coach Doug Marrone with his college quarterback.
9 N.Y. Jets: DE Ziggy Ansah, BYU -- He played out of position in college and had only 4.5 sacks. But he was a terror in the Senior Bowl.
10 Tennessee: OG Jonathan Cooper, North Carolina -- Times have changed. Guards are no longer undervalued in the draft.
11 San Diego: OT D.J. Fluker, Alabama -- New coach Mike McCoy can't do what he wants if Philip Rivers head explodes in anger after another third-down sack.
12 Miami: CB Xavier Rhodes, Florida State -- They select a big corner to replace the big corner, Sean Smith, they lost in free agency.
13 N.Y. Jets: WR Tavon Austin, West Virginia -- The only problem (OK, not the only problem) is the Jets have nobody to throw the ball to him.
14 Carolina: DT Star Lotulelei, Utah -- It's difficult to imagine he'll last this long, which means he could be a good trade-up target.
15 New Orleans: DE Barkevious Mingo, LSU -- The Saints need only look a short distance up the state to find the best fit for their defense.
16 St. Louis: S Kenny Vaccaro, Texas -- This is how the Rams fill the void left by Craig Dahl's departure.
17 Pittsburgh: OLB Jarvis Jones, Georgia -- He knows how to get to the quarterback, as shown by his 28 sacks over the past two seasons.
18 Dallas: DL Sheldon Richardson, Missouri -- Defensive players from Missouri are not a bad way to go. Just ask the 49ers.
19 N.Y. Giants: DE Tank Carradine, Florida State -- If he weren't recovering from a torn ACL, he'd probably already be long gone.
20 Chicago: TE Tyler Eifert, Notre Dame -- New coach Marc Trestman adds a nice chess piece to his offense.
21 Cincinnati: OT Menelik Watson, Florida State -- Whether Andre Smith has a long-term future or not, the Bengals have a need at offensive tackle.
22 St. Louis: WR Justin Hunter, Tennessee -- The Rams have a chance to challenge for a playoff spot, but they need to get Sam Bradford a playmaker.
23 Minnesota: DT Sylvester Williams, North Carolina -- The Vikings see a chance to grab the next dominating inside force named Williams for the defense.
24 Indianapolis: DE Sam Montgomery, LSU -- Expect the Colts to look for a pass-rusher, and that's something Montgomery does very well.
25 Minnesota: CB Desmond Trufant, Washington -- With Antoine Winfield going from Minnesota to Seattle, Trufant makes the reverse commute.
26 Green Bay: S Eric Reid, LSU -- His job for Week 1: Make sure Colin Kaepernick does not get past him for 180 yards rushing.
27 Houston: WR DeAndre Hopkins, Clemson -- Andre Johnson gets a sidekick that actually makes defenses take notice.
28 Denver: DE Datone Jones, UCLA -- After Elvis Dumervil's bizarre exit, the Broncos get a lineman who can play a number of different spots.
29 New England: CB Jamar Taylor, Boise State -- Remember when Bill Belichick was known as a great defensive coach? He needs help in the secondary to regain that reputation.
30 Atlanta: TE Zach Ertz, Stanford -- Eventually, Tony Gonzalez will actually retire. And when he does . . .
31 49ers: CB D.J. Hayden, Houston -- Of course, there's a good chance the 49ers will trade up for a defensive lineman, such as Tank Carradine. But if they stay here, this is Trent Baalke's pick to fill a need before it becomes a huge need. Tarell Brown is in the final year of his contract, and Carlos Rogers has to have a big season or he will not return in 2014. They can address defensive line with their next pick at No. 34 (Kawann Short of Purdue?), and safety at the end of the second round.
32 Baltimore: LB Alec Ogletree, Georgia -- I suppose Manti Te'o will get the call at some point in the first round, but not in this mock. Feel free to call it a hoax.
