Nice pick up, I never thought about that. Since, grad assistants cannot go out on the recruiting trail then either two things have happened:
1. Papuchis will be the next DC; leaving one spot for a graduate assistant to move into a full time assistant coach. This would mean as stated above that Marrow will be our TE coach and Papuchis will be our DC.
OR
2. Since we lost our DC, Nebraska might have asked for a petition from the NCAA to have Marrow go out and recruit, thus placing a interim tag next to his name, since our coaching staff has one available spot.
If I had a gun to my head and had to pick to see which one is more plausible my answer would be number 1; but who knows....
