Based on what evidence? I don't think you people realize how near-perfect Worley managed the game last night.
Every time he made the read-option to hand off or take it himself, it was 100% the correct decision. You could clearly see the difference when Peterman came in and made the wrong decision almost every time. Peterman is faster and more nimble then Worley but yet got blew up almost every time he decided to keep.
As for Dobbs, he obviously did not get a chance to show us anything. However, the point I'm making is that it's clear why CBJ has these QBs ranked where they are on his depth chart. Either Dobbs is even less ready then Peterman at making reads/decisions or he wants him to RS, or both.
Just let CBJ make the right choices, so far he seems to be making good ones.
