The article quoted in that thread rated his pass-blocking abilities, not run-blocking. I daresay that the TE in this offense won't be doing much pass blocking.
Rosario is not a true TE, he is more the HB type. One of those times that Foxy and co. actually played to a players strength. Move him around where he can either block like a FB, or run routes like a conventional TE.
The TE position this year is going to be interesting. Been a long time since a TE was actually involved in the passing game. A recieving threat at TE occupies a LB, which can help in the running game. And we are going to need a running game to keep teams honest.
I think that is what I mean. And GOOOOO PANTHERS!!!!!!!!!!!!!!
