Draft Express has Jordan Bell going 42. I don't see anything special about Bell and he's already 22. I certainly wouldn't trade up for him.
I agree about Tony Bradley being a potential steal in the 2nd round but I think if he doesn't get a 1st round guarantee that he'll withdraw from the draft and return to school. He'd probably be a mid-1st pick in the 2018 draft. If it didn't cost too much, I'd trade up for a late 1st to take him.
