Bledsoe absolutely had no touch on the short passes, I've always felt that way. But those stats are, as pointed out, fairly meaningless.
Our failure to execute a real screen pass stemmed from two things: Bledsoe's inability to throw the short touch pass, and the entire offense's inability to set one up.
I'm not sure where the breakdown always was, but it sure seemed like every time we tried to execute a screen pass, the defense was all over it. The debacle in Baltimore is a good example. Bledsoe's throw sucked, but it was compounded by the fact that the entire Baltimore defense knew it was coming and was in position to make that play.
