Gotcha. He won’t play meaningful snaps at TE but he could be useful on special teams like a blocker on FGs plus the scout team.
I am all for taking as many PWOs as we can get. You never you may just find a diamond in the rough.
Tackle? As in Offensive Tackle? Kid is listed at 228 lbs, at that weight he wouldn’t even be a decent scout teamer.
If he wants to be walk-on bring him in at TE.
