Leaving the starters in

I think many of us were surprised that, unlike the Hawaii game, this game versus an overmatched opponent wasn't used to get lots of the backups and younger guys in to get some experience and save the starters once the game was well in hand.

Was anyone else surprised that Harbaugh left so many of the starters in so long?

The broadcast team also mentioned several times sbout leaving Speight, Pepper, and company in.

Did it have something to do with feeling that the effort was not at a level the Michigan coaches were happy with?

Did they also feel, like Scott Frost, that UCF was "outhitting" Michigan?

Did they feel it was necessary to get the run game working, and to address the problems that flared up on defense (QB runs, losing contain, some poor angles) ?

Or was this something like the four hour practices- planned in advanced to get the starters mentally and physically ready to play a full games when necessary later in the season?
