Which was the worse look? (DA vs Smith)

Smith was within his right to be mad but DA should have said something to the effect of "hey look.. the players wanted Jamaal to score a TD and that's what they did" and left it there.

Instead he went into the press conference and made it worse.
Erik McCoys answer was thoughtful and conveyed everything anyone needed to know about what happened. Maybe we should let him handle the post game pressers
