Luckily, the two guys behind Johnson and Hilton aren't very big. Moncrief (6'2) and Dorsett (5'9). It should make things a little easier for Darby when Hilton is put in the slot against Robey.
This is what I have been thinking would be the best thing to do. Put Darby on the smaller, faster Hilton and give him a little help and Gilmore alone on the bigger, stronger Johnson.
I think KTD nailed it with his take. EJ will likely be the guy to take over #1 if TT gets hurt or plays badly a few games in a row. Cassel will be backup for emergency in game play. Hopefully it's not just talk that all 3 help each other to get better.
