I would also pull Blanton ...
Unless Harris has improved a ton and has put on weight he's just too easy to move.
Case in point... I'd put Kupp as TE2 before anyone we have because he's a tenacious blocker. But I think Blanton can pull it off because of his size. He was a willing blocker at mizzou and won with size ... not as easy in the NFL but we're not talking about a lot of snaps.
All that said, using Harris would afford us a few shot plays in the red zone in all likelihood...
He might develop well enough with playing time that we could count on him for spot duty throughout the year.
