If HS testing numbers are to be believed, Martells 20 yard shuttle of 3.96 is better than the Braxton Berrios's shuttle at the NFL combine of 4.07. 20 yard shuttle has a strong correlation to success as a WR (moreso than 40 speed). Martell might have to accept that he has better NFL prospects as a WR than QB (doesn't mean he can't be an effective college QB with the right scheme, but it's not a great fit with Enos's pro style offense). With Martell's level of quickness he could be difficult to defend out of the slot.
