Sanchez consistently misses open TD passes and ends up throwing int's instead. I've honestly never seen a QB turn so many open TD's into interceptions, it's actually amazing when you think about it. Just about all of those int's are from slow decision making and then poor mechanics when he tries to hurry up to catch up.
If Sanchez made the basic passes that Sparano asked him to make and completed the open TD passes, then the offense would actually score some points. There is no way you can blame this mess on Sparano.
Did you not hear how incredulous Marv Albert and Rich Gannon were when Tebow ran THE SAME play for the fourth time!? Not much OC creativity there.
