It's obviously a risk because he's coming from D2 but he's a ridiculous athlete/tackler. The only weakness is coverage, if he improves there who knows how good he can be.
For me, with all the recent developments and how often teams are playing 3 safetys I think it's worth the risk. The floor is a box safety/LB but I think given the current NFL the risk is worth it and hope he improves his coverage even a little bit. Even if he only hits the floor and is effectively a LB I think that plays in today's NFL
