Ever wonder why most coaches reserve their comments on anything before watching game film? It's because it allows them to look at a flaw from every angle. They can watch the OL, then the WRs, then the QB, etc. and get the full picture of why something worked or didn't. Apparently, when the coaches watched film of the preseason games, they felt too many of the breakdowns were on Volek. As I have mentioned before, I saw Volek check down to a five yard pass while Roydell Williams ran free down the sidelines. That is only ONE instance I saw because I was focused on Williams and not Volek. Most of the time, we watch the ball and don't focus on one receiver. I still think there had to be some issues beyond Volek's play in the preseason games which caused this chain of events to unfold. But if Fisher/Chow noticed a trend with Volek missing reads and it wasn't improving throughout camp and the preseason, then bringing in Collins makes sense.
