Not many true Fr TE ever get to the field at Iowa. Fant did, and Fant was getting some snaps before Kittle went down to injury. Iowa's passing game was pathetic or Fant would have had even more catches.
If you wanna make a side bet, I will. Fant > Allen this year. Let me explain why this is a horrible bet for you to make on Allen.
1) Even if talented he is still seeing the field for the first time vs FBS talent
2) You don't even know how CMC will even use his TE
3) Fant is clearly Iowa's #1 TE now and that alone carries with it a bunch of opportunities, being on the field a ton and a lot of pass catching opportunities.
I will make this bet, it is a no brainer for me, on the other hand you might wanna think long and hard about it.
