I could see Thomas and Moss rotating the flanker/split end duties. Sometimes it benefits Moss to line up behind the line of scrimmage so he can have a few extra steps to juke the corner. He's so small it's tough for him to out-physical larger CBs.

The funny thing is, until someone proves otherwise, Chris Cooley is our #1 pass catcher. His durability and consistency are awesome.
