Weak answer? BS. Explain why when Trent makes a mistake, he crawls into a shell and reverts back to checkdown mode. When he got pulled in the Tennessee game, did you see him put up a fight? No, he just went to his golly gee whiz mode.
If you don't want to call it heart, fine. Call it mental toughness. Call it whatever. Trent is just happy to be here as a player, and that's not acceptable.
