This may be a stupid idea, but at this point, what the hellz. Trent seems to struggle when he gets blitzed and gets that dear in the headlights look. He can't shake this off in games.
So why not let him practice in these situations. Let our D have the go ahead to go after him and knock him on his ass on every pass play. I'm not saying they should kill the guy but let them knock him down. He's been untouched and off limits in practice. He probably gets too used to this. Maybe this way he'll shake off the dear in the headlights mentality. Rough him up a bit and often enough and maybe he'll fight through it and start making some plays. And if he gets injured? Meh, what's the loss at this point?
Something needs to be done with him.
