Gs McCormick and Bortolini (maybe C) are still available. Either would be great fits in the 4th. If they go for someone like Foster instead (i.e. another tackle), that might be pretty telling on Tom's position next year.
TJ Tampa (as previously noted) would be great. Hicks at safety seems to be good value, but I'd almost prefer a later safety that is highly athletic with limited experience (high ceiling, low floor type) to take a shot on. McKinney, Bullard, and Johnson (with Nixon too) is a pretty decent safety room. Sign Rudy Ford and that high-end late round pick puts us in pretty good position.
LB room is pretty well set - McDuffie, Walker, Welch, Wilson, Cooper, and Hopper. Not a ton of experience in the room, but some upside and athleticism.
