Mike Davis is a solid WR. He never had a good QB in his career, he had Garrett Gilbert his freshmen season, probably the worst college QB I've ever seen, Ash and Case in his sophomore season, Ash in 2012 (decent, but nothing special), and Case McCoy last year. If anyone manages to grab him in the 5-6 round, he'll be a steal.
I like Robert Herron, dude destroyed Texas with 173 yards and 2 TDs, but then again our defense was AWFUL that year.
Marcus Smith is a very good player, he'll be a steal in the 3rd round.
Don't think Seantrel Henderson will ever amount to anything in the NFL, he just doesn't care about football IMO.
