It was Jim Harbaugh's first season as head coach of the 49ers.
The 4-1 49ers were in Detroit and scored 10 points in the final 5:29 to beat the Lions 25-19.
An excited Harbaugh got a little too agressive during his postgame handshake with Lions coach Jim Schwartz. The two had words for each other and had to be separated.
Six years later, Harbaugh took the blame for what happened and said that he and Schwartz have patched things up.
"I went in too hard on that, too aggressive on the handshake. I've since changed that. Not doing that anymore. Can't blame him. I went in too hard. And you respect him for taking exception. We've talked, and we're good. We're back to friends. There is a protocol in a postgame handshake. I've been there as the winner. I've been there as loser. You just, 'Hey, nice game,' then go celebrate. Premature celebration there, in the wrong," Harbaugh said Tuesday on Barstool Sports' Pardon My Take podcast.
Harbaugh sounds like he's learned his lesson from that incident with Schwartz.
"The postgame handshake isn't the place for anything. If you're bitter, than change the I to an E. Don't get bitter, get better. Nothing's really changing at the postgame handshake. Just professionally shake hands and go on your way," Harbaugh said.
Harbaugh moved on from the 49ers to coach the Michigan Wolverines. Schwartz coached the Lions through the 2013 season and currently serves as the defensive coordinator for the Eagles.
The Warriors possess four 2017 All-Stars, three 2017 All-NBA team members and had the highest-scoring offense during the offense. They are 12-0 this postseason and have won those 12 games by an average of 16.3 points.
The Celtics lost All-NBA point guard Isaiah Thomas for the rest of the postseason and don't have another All-Star on the roster.
But for Cavaliers head coach Tyronn Lue, it sounds like he has an easier time scheming to defend the Warriors.
"The stuff (the Celtics are) running, it's harder to defend than Golden State's (offense) for me, as far as the actions and all the running around and all the guys who are making all the plays, so it's a totally different thing. Like, they hit the post, Golden State runs splits and all that stuff but these guys are running all kinds of (stuff). And Brad's (Stevens) got them moving and cutting and playing with pace and everybody is a threat," Lue said Wednesday, according to Cleveland.com.
The Cavs rallied to beat the Celtics in Game 4 on Tuesday night to take a 3-1 series lead in the Eastern Conference Finals.
Despite the commanding series lead, Lue isn't looking ahead of a potential NBA Finals matchup with the Warriors.
"You can't. As much as you want to, it's not over," Lue told reporters.
The Cavs have a chance to wrap up the Eastern Conference Finals on Thursday when they face the Celtics in Boston.
The NBA Finals begin June 1 in Oakland.
