Earlier fears about UFDA washout may be unwarranted: From a JSO story:
Undrafted rookies Donatello Brown and Geoff Gray look like they have a chance to make the roster. Brown, a cornerback from Valdosta State, has decent size (6-0, 190) and speed (4.50 40), and he competes every down. Gray (6-5, 315), a guard from the University of Manitoba, is a mauler as a run blocker. He has a ways to go in pass protection, though, because he’s too aggressive and compromises his balance by reaching for his guy.
