You want your best five on the field. If Simmons can regain his form, I would say Simmons at RG with Wood at C is a better combo than Hangartner at C and Wood at RG. I would also like to see Butler on the bench as a backup.
In my perfect world:
1st round LT, Levitre, Wood, Simmons, Bell/Meredith/Scott with Hangartner, Butler and the better loser of the Bell/Meredith/Scott bunch on the bench. This of course would mean that one of our young tackles gets to work over the offseason and is good enough to take the job away from Butler.
