If A.Smith is healthy for the superbowl matchup against the packers should just use him as a backup with a limited role, Backup with big role, or a starter?

I think we shouldnt mess with anything going into the game. Hood is finally breaking out and doing a gj in the 3-4 defense. I know Smith is a great linemen for the steelers but I dont think he should start(which i doubt) and since he prob will be a sub, how much playing time will he get? About 10 snaps on defense? I dont know what the plan is for Smith. I know hes not 100% by any means at all but do we play him at all if he is about70-80%?
