To be fair to the team you root for let's take out the two 5 interception games from Sanchize you mentioned.
Qb1 86.4 rating, 3,618 yds, 20tds, 15 ints, 64.5 comp%
Qb2 69-75 roughly, 2,444 yds, 12 tds, 10 ints, 53.8 comp% that's if two games worth of picks hit the ground.
He trailed such notables in passer rating as Brady Quinn, Ryan Fitzpatrick, Chad Henne, Marc Bulger, Matt Cassell, Hasselbeck, Garrard, and Orton.
He did outplay Stafford, Freeman, Delhomme, and Russell though. Yep, 28th in passer rating last season, J-E-T-S hype, hype, hype
