Short answer Raiola is a better QB that increases our chances of winning games than Haarberg.
1. That why you schedule UTEP.
2. You need a passing game to win, you don't need to have a running QB to have a successful running game.
3. The OL is improved and Raiola isn't short confidence.
4. Redshirting Raiola is a waste as he won't be here 4 seasons, let alone 5.
5. Who cares where the QB was born.
Finally if you want to make a case for Haarberg at least spell his name right.
