Clark is way to green to make the 53 but he is why the NFL has the practice squad. A year or two on this to continue to learn the game will only make this kid better.
I agree "GBP" but worry about a guy with his physical ability. If he struggles the rest of the way through pre-season then the PS is a good option. If he flashes some ability in those games, some team who isn't deep might decide they can use him as their #5 or #6 guy and "stash" him on their roster for a year.
