In Steve Youngs first 4 seasons in the league, he threw as many or more INT's than TD's 3 times. Sanchez only did that twice. Stay tuned.
I've never thought Sanchez would be successful in the nfl, from the day he was drafted. However, he is in a very friendly system and I believe he can keep the ship righted until Foles comes back. I just don't see him becoming a hall of fame qb.
