Many NFL players are married with kids as well, and no one claims about lack of aggression or whatever with them due to wife, family and home. So I do not see it.

It is philosophy and technique. Basically, they need to play more physical. Our line is too finesse. Bama was physical and tried to manhandle the D, not just react to them. It is a mentality. Not about just trying to stop them, but about trying to dominate the opponent.
