Man if I had to go with one on the list I'd probably take Malik Hooker. I'm really intrigued by Obi though. He has the size and athleticism that we desperately need against the Patriots.
With his size speed combo he can develop like Byron Jones and would be one of a handful of guys who might be able to slow down Rob Gronkowski.
In addition, he is a bigger Shaq Thompson who can be the LB/S combo that McDermott really likes to have on his roster. A really flexible, versatile behavior.
Anybody who thinks this guy is gonna be there at 44 is nuts
