As far as the screen passes , yes he's had problems , but let's be honest how many screen's have we seen since Rex took over. It doesn't appear to be part of his/Shotty's/Sparanos offensive mindset. There will be some who argue , well they don't throw them because Sanchez sucks at it , but its a true chicken & egg conundrum maybe he sucks at it because its not practiced much. I believe that the offensive plan that was in place for 4 years under Rex has been don't lose the game for us on O and the D will save the day. In this era of the NFL which highly favors the pass game , its a travesty to have a FO/CS so rooted in its stubborn ways to not see this. I also believe by bringing in MM & Lee the Jets from the top down are finally adhering to an approach of let's take advantage of the rules and become an attacking style offense.
At the end of the day/season Sanchez may still suck , but honestly I don't think we've seen enough of him in a real offense to fairly evaluate what he may be. People will point to 52 turnovers , 50% completion % , worst QBR etc...... but what do those stats really mean in an ultra conservative G&P offensive approach that forces a team to consistently play from behind and in adverse passing situations.
