Quickie halftime impression of Troy Smith. Good long throw arm. Better than Alex. More adaptable than Alex. More aggressive than Alex. I’m not sure how good Troy is on the subtleties of the game. He seems to hold the ball too long sometimes. I’d like to see him run more. That would add something to the 49ers attack. Based on one half he seems an upgrade over Alex. Does that mean he’s the answer? I have no idea yet.
