I honestly believe that Daniel has a shot to be that edge opposite Floyd, long term. He has the talent he just needs to develop it, technique, i.e. hand use, arm, hand play and bend. Show he can be stout at the POA on outside runs, and understand and execute zone pass defense concepts. It's a lot but once he begins to get it the process will go faster as he's building upon not trying to learn new stuff.
IMO Hardy is the sleeper in this draft. Others are much easier to project because they are closer to being complete players. It's a long difficult process but the payoff can be enormous for the player and the team.
