If he works as hard as he always does, he will crush the combine, and get drafted (probably a lot earlier than people on here think). If you don't think he's NFL caliber you obviously haven't watched some of his runs this year.
Just FYI for stats people:
Neal is 94 total yards away from being Top 15 all time in All-purpose Yards at UT
Neal is 62 rushing yards away from tying Charlie Garner for 12th all time.
11th all time is Travis Stephens, here's a little comparison between the two:
