I do not see the improvement in Worley. At least 70% of his throws are behind the receiver or too high/low. Dobbs seems to hit the receiver in stride. Maybe Justin considers throwing to the outside shoulder a good thing, but it looks more like he is just missing far too many throws.
My .02 worth for free!
You are seeing what you want to see. Dobbs isn't throwing it well either... and I like all three guys. Peterman may be getting 1st team reps because he's throwing it better. He seems to be doing so in the clips we see.
