Moala is a big DT, likely a NT, but really slow, and a raw athlete
A good sized DT, run stuffer, good tackler. Not the fastest, and would need to bulk up more to be a NT
Coleman is fast and speedy, gets seperation, but can also make easy catches. Has problems at times with difficult catches, and coughs up the ball too much
Carrethers is a big body Lineman, run stuffer, a NT in the NFL, good tackler overall, just slow.
Sutton is a tackling machine, has decent speed, and a good pass rusher. But he does have some weight concerns, is a 3-4 End or maybe a NT? Plus his production was down in 2013. But I expect him to be a Top 50 pick.
