After having thought about this whole situation between Carr, his receivers and the coaches, I feel there is enough culpability to go around. DA, Pete, Carr, MT and Olave all have a hand in this mess. 3 of those had normal football problems, 2 really stirred the pot. This post isn't solely about DC and MT and to be fair these are some hot takes and I'm opening myself up for some backlash, but it's just how I see it in hindsight.
In order of least culpable to most:
1. Olave. He definitely needed to hear about running lazy routes as a decoy. He was the top receiver and he knew that. When the defense doesn't see him as a target, it makes it much harder for the other guys and Carr to make a play. The way he got that feedback was absolutely awful and deflating.
2. Carr. He should not have reacted as strongly to Olave's weak decoy route the way he did. It was a bad look on the field and should have been something they were looking at on the sidelines as a learning moment for both of them, but Carr reacted with anger and that was dumb. That he clearly repeated that with the O Line and McCoy reacted to it shows that Carr has that to work on.
3. Pete Carmichael. He simply did not have this offense playing together until really late in the season and was a weak leader of the players. He needed to suss out these problems in camp, preseason and practice instead of having players blow up on each other during the season and especially on the field during games with the world watching. He wasn't a first time coach. He's been around forever and watched one of the best to ever do it close up. No excuses for how splintered his offense was this year.
4. DA. He is the first to stir the pot on the Olave thing. He should have lied and said "I didn't see it and would have to watch the tape. Next question". The way he talked post game about it put the focus on Olave and that was wrong. On top of that, this is his team. He did not get the right person to lead the offense and left it in the weak hands of PC which didn't work the year before and blew up in their faces this year. He also had other people in the building that could have done a better job and he chose to ride with Pete all season.
5. MT. He is the ultimate pot stirrer. If his problems were isolated to the play where he was injured it would be one thing, but he made it about a lot of other people that had nothing to do with that and tried to drive a wedge between players / other players and players / coaches. This is straight up bad teammate stuff that only he was doing.
4 of these guys have some real personality defects. DA has a knack for saying the wrong thing and throwing people under the bus publicly while deflecting from others. Pete just isn't a very good leader, which would be fine if he was in a supporting role, but his role required him to lead. Carr is an immature hot head that comes off as disingenuous when he talks and always seems to be making light backhanded comments that could be taken the wrong way. MT is just a big baby and there is no excuse for anything he's done regardless of how he feels about the play that resulted in his injury. He's a literal locker room cancer.
Only Olave conducted himself with class and maturity through the whole season. Which is pretty pathetic considering he is the youngest of the bunch with the least experience in the NFL. The mistakes the other made you'd expect from someone like Olave, but he was the grown up here. He was also robbed of the opportunity to improve with constructive criticism and instead seemed checked out for a few games. I honestly feel bad for this guy.
