A team's closeness and culture is a tangible advantage on the field

I always feel the tighter team, the closer team, has an advantage over the team that's not as tight. And the only way you do that is by hanging here, spending time together. I like to put ping pong tables in there just so people kick it and they don't go home right away.

Defenses never actually 'caught up' to the zone read; execution and health just failed

Personally don't think [defenses] ever did [catch up]. It was the lack of being able to continue doing it... There's no hey defense learned how to stop it. Yeah, they just have to play simpler which allows you to open up everything else.

Jimmy Garoppolo is an elite thrower with exceptional release speed

Jimmy, he's an elite thrower. I think everyone can see his arm talent, how quickly he can get rid of the ball. Even if you don't block very well, he can speed it up so fast that it's very hard to get to him.

Having a fullback allows the offense to dictate the game to the defense

I like to dictate what the offense wants to do. And when you don't have a fullback in the game, the defense can dictate it a lot... When you have a fullback in the game, it doesn't matter what the defense does. If you want to run it, you can, and they know that.

I regret throwing the ball on 2nd and 10 in field goal range during Super Bowl 51

The one regret I had is after we got down there was throwing it on second and 10. I wish I just ran it. But I also didn't plan on us getting a sack. We got four guys out, thought we could end it right there, and I thought if it wasn't, we'd throw it away, and we didn't.

The holding call on Mohamed Sanu in Super Bowl 51 was a suspect flag

Mohamed Sanu got us right back in the field goal range, but our left tackle had a holding kill, which put us in a third and 30... Mohamed Sanu beat man-to-man coverage, and it was over like that. But then there was a flag there, which – It still is a suspect flag, but it is what it is.

Johnny Manziel was set up to fail by being drafted higher than his production warranted

I thought Johnny, you know, he was put in an unfair situation where I thought he was taken higher than what he could produce. And that's a lot of pressure on a guy... I think he was set up to fail from the beginning.
