A look at the list here as they all hit the field this weekend:

The upcoming football season could be longer than any season on record. Now more than ever, we need to get depth.

Where I'd like to see depth used in the first two games:

QB: Locke has improved. I want him to see that translate to the field early this season.
RB: Let one freshman get meaningful reps in each of the first two games. Acclimate Walker. Limit Mellusi.
WR: Rotate generously on the outside to see who can catch 50/50 balls. Acclimate Trech. Limit Pauling.
OL: Get experience with alternative combos using 2nd team. Get lots of 2nd team reps.
DL: Limit your workhorse to the degree you can. Play Howard and Johnson as much as you can
