Doesn't really matter. If a team isn't going to use a pick on him, they aren't going to poach him off the practice squad to add to their active roster.
Dallas using a S at the nickel makes the math a lot tougher because they aren't likely to carry more than 3-4 outside CBs.
S - Thompson, Locke, Hooker, Bell
Slot - Downs, Steward/Kendrick
CB - Bland, Durant, Revel
If they keep 10 DBs, that leaves a competition between a lot of guys that's most likely going to come down to ST (Goodwin last year). Moore isn't going to lock down a ST spot, so I don't see the path for him to be on the opening 53.
I like his talent, but outside of injury I don't see it unless he has a ridiculous camp.
