I haven't seen either loss, so I'm just going off assumptions from looking at the box scores. I think losing Parr hurts us alot more than anyone initially thought. He may not have been lighting up scoresheets, but without him there's been a big dropoff in the QB play.
Parr's TD / INT ratio was 11 / 7. Brumbaugh's is 2 / 6 as a starter. Interceptions hurt enough, but it hurts the run game too. Defenses can now stack the box to stop Hines and Allen. Hines averaged 4.5 a carry before the injury to Parr. He's down to 3.1 since. Allen was at 5.1 before the injury, down to 4.6 since.
On the other hand, in hindsight maybe we weren't that good to begin with. I know we all had high hopes after the strong finish last year. Looking at our early results indicates maybe we haven't reached those expectations all year long. We got blown out by Youngstown State and UNH, who are at or below 500. We eeked out a wins over winless LIU and 1-10 Wagner. Perhaps we weren't that good even with Parr.
