I think he has really only had one strong performance all year -- unfortunately that was against the Bills. Yes, he has been in the right place at the right time. I have no doubt there are a bunch of other QBs the would make the Jets a better team.
Regardless, for the Bills to beat the Jets, Sanchez or not, we have to stop/slow down their running game, force them to throw the ball, and do something with our own offense. if we can do that like the other teams that have beat them this year, we will have success.
