I know a few basketball players had success playing the TE position but I don't think it's as easy as ESPN makes it out to be.. Alot more in being a TE than just jumping in the Endzone and making grabs.. Running crisp routes, getting separation, blocking, the learning adjustment, etc. Plus I don't think he can handle the physicality of the league despite his freak size.
Forget about him playing DB either. Majority of the DB's are faster than him anyways.
I don't think he'd be good or anything but that's me
