Agreed, and when is it best get younger guys game experience and figure out what else you have in the cupboard? Against the weaker non-conference matchups, or after a mid-game injury, down a touchdown in a rivalry game on the road?
My gripe really isn't over just this Miami game, it's in the pattern going back to last season even when the games were clearly decided either way and for some reason, the Gophers would not even get the backup QBs a few snaps in the final minutes. Tanner did not benefit from taking those snaps and further, you could even argue there was some level of risk for him to get injured at garbage time.
