I had thought about this before because he is very impressive at both WR and Safety. He is one of my favorite signees in this class.
It is even more impressive when you realize that those highlights are from his 1st season playing HS FB. The instincts he has and plays he makes are phenomenal.
But, IMO he is just too talented at WR to put at safety. Of the incoming class, I think of Lockhart, AJL, and Waters as lumped into one group as being a similar type of WR/Athlete. I see any of those 3 as able to find some success on offense or defense if they start their careers at one position and stick to it. Of those 3 I think I would most want Waters to try out safety. I think he is a natural football player with the instincts and athleticism to succeed on Defense, and I think the other 2 may have a little bit more to offer in complimenting the rest of the incoming WR class
