I don't think Moudy actually played very many series at LG, I went back through and tried to count and I think it was only 1 series in the first half (the 4th drive TD) and 1 in the second half (no points). The second line played better in the second half but that also could have been a result of Northwestern getting worn down, the first line didn't really play that bad. The offense was stalling because Armstrong was 6/13 passing in the first half with that group. The pass protection was good all game, he was never under any pressure except when he dropped the snap. If he would have hit a few more passes, the first line group would have looked better. There was also a nice 8-9 yard run in the first half that was called back because Alonzo Moore didn't line up correctly, that was a big play that put them behind the sticks. The holding call on Cotton was borderline and he came back and made 2 nice blocks on the next 2 plays. Cotton was also stonewalling his guy in pass protection all game, he looked pretty darn good. Keep in mind that Cotton was also on the field during the 3 rushing TD drives in the second half, not Moudy. Sterup also came back in for Price on the drive they ran it 9 straight times for the TD.
So overall, the second line did play a little better in the running game but I think its been a little blown up on the board and in the media on how much you can really equate the second half success to the second string line. Everybody played better in the second half, most importantly Tommy was hitting and receivers were catching the 3rd down balls.
