Favre is damn near 6 inches tall than Lee. I wouldn't worry about it. Lee sucked balls. He didn't even put up huge numbers in Juco ball. All it takes to make Juco AA is a damn nomination these days. Favre would put up insane numbers in Juco ball.
He may not be a savior, but Favre is going to be a better QB than we've had since Fant (not that it's saying much). Relf, Russell, Stegall, Favre- that's better than Tyson Lee, Relf, Russell, & Stegall. Hell, we've improved the QB position. Hopefully we can continue to do that each year.
