Go back and watch last year's games, and you'll see that the route running was not good, blocking was sub par, and there were too many drops. A lot of that had to do with Cahoon, I think, but the other issue is that there aren't really any elite athletes among that group right now.
You can make up for lack of top-end athleticism with good technique, and that's going to be key for this group to succeed. Hopefully Fesi is up to the task.
