Last year, in one of Iowa's lowest TE productivity seasons in a decade (due to losing 2 x 1st-rounders to early entry), Iowa still outproduced Nebraska's TEs by about 200 yards. With regard to TE snaps, I am sure Iowa TEs had more than double the opportunities to get on the field than Nebraska TEs had.
Iowa has had 10 TEs drafted in the last 20 years (and 5 UFAs). Nebraska has had 1 TE drafted in the last 20 years.
Iowa seems to be stockpiling offensive skill position talent and elite OL in this class.
Seems like a straightforward decision.
