This guy gets and has gotten more undeserved hype than any other player in recent memory IMO. Even now people are hyping up where he's going to go like he's going to be a major difference-maker. In his younger days he got by due to his insane athleticism, he was never a dominant passer at anytime, and now that he's lost a step, he's simply a mobile quarterback with less than average accuracy and a penchant for turning the ball over.
The best season of his entire career passing-wise was 2010. He threw for 3000 yards, 21 touchdowns and 6 interceptions...essentially in the realm of "game-manager" stats. In other seasons he had substantially more turnovers. His career completion percentage is 56.3%.
I just don't get the hype, he had a monster season in 2006 where he ran for over 1000 yards, but then his passing stats were garbage. As a GM, I'd much rather invest in a younger, more reliable, less turnover prone Alex who may not have as much big play potential, but he'll produce essentially similar amount of passing yards with less interceptions and a better completion percentage.
