Paradis, Bruce Irvin and Dontari Poe are probably all in the discussion with some of the success from previous teams. Hogan possibly too, although I am not sure long he was with NE. Olsen is probably up there. Maybe even the special teams guys like Jansen or Gano.
This question is pretty difficult because it requires us to know a lot about players previous team success prior to being Panthers.
Moton played one game of his career at LT. He did look good. Little has been a LT since day one. I'm not discounting Moton at all but if you are going simply on how players project to positions then Moton is your prototypical RT and Little is prototypical LT.
It appears they are going to let Moton settle in to the RT and say barring some kind of emergency.
I would trust Matsko and Wharton to have a good idea where players will do best.
