???? Every team will start the QB that gives them the best chance to win. Very seldom is that a rookie, only if the team has really bad backups. Even then, starting a rookie is generally a bad idea. even if the rookie is really really good. Peyton Manning was 3-13 his rookie year. I think he turned it around to 13-3 his second year.
And he came from Tennessee. Even rookies from major colleges have trouble with NFL-level defenses. Rookies who did not come from major college programs, say a rookie from San Diego State, would have even more problems.
Are you really this obtuse, or are you just wanting to act like a moroon because you're bored or something?
