Was any one of his games this year any better than Western Michigan his Freshman year?
It's impossible to say right now how much better he is, his stats simply aren't comparable year over year given the significant change in SOS variable.
It will be interesting to see how he does against NFL speed and pressure surrounded with NFL talent. He can make all of the throws given time, but can he do it under pressure? Mixed results in college, made some bad choices under pressure. Difference between good and great.
