"It's all about the chemistry of the team rallies around the quarterbacks," Jackson said. "You don't want to have two factions: A Cardale team and a J.T. team. Everyone has to be on the same page.
"There's no question there were guys who liked me and guys who liked Joe. I don't think I was as mature as these two guys, quite frankly, and the team was split at times. While we were winning it was good, but when there was a struggle, it could be bad."
Playing quarterback is about confidence, and Jackson said it's almost impossible to maintain it when you don't know if you're in for the next series.
"If we didn't score by at least the third drive that I'm in, I'm probably going to be on the bench, so there's decision I'd make to force a ball that I wouldn't do if I knew I was playing the whole game," Jackson said. "That's the challenge."
