There's a lot of talk that Harold Fannin Jr will actually end up playing as a WR. Marques Colston was originally listed as a TE in the 2006 draft. How do people see Fannin's best position?
He was drafted as a WR and played WR at Hofstra. It was a mistake for him to every be listed as a TE anywhere which led to Yahoo keeping him TE eligible in fantasy football creating a hack that let teams place a stud WR into a TE position.
With all that said, we have a converted WR on the roster who played some WR again at the end of last season. Fannin could potentially occupy the same space and for that reason, I'd almost prefer a more complete TE.
Another player occupying that WR/TE space in the draft is Oronde Gadsen II who's listed at 6'5" 236lbs. Reading up on him, it looks like teams have asked him to workout at different weights so he was a different weight at the East/West Shrine Game, NFL Combine and Pro Day.
There's discussion out there about Colston Loveland being more of a X or split out TE than an inline TE. Mike Gisecki is being use that way with the Bengals and he's found success there as a big weapon for Burrow.
