I covered a couple of their games last year and did a couple of them this year. For some reason I thought he was more of a Tavon Austin like build, but he has decent size. Listed at 6'1" 190 lbs. Could put on a little more, but I really like what I have seen from his as well. Like you said, it looks like he could fall much further than he should, and I hope the Rams can scoop him up. I've seen people say that he plays in a high volume offense, which inflates his numbers, but he has only averaged 56 plays per-game this season. Three of his best games were against top-70 defenses and two of those were top-50 in Houston and Middle Tennessee.
Here are his career numbers at WKU(impressive):
227 receptions on 314 passes thrown his way. 72.3% completion rate!
3,949 Yards
17.4 yards-per-catch
41 touchdowns. 17 in each of the last two seasons
14 drops
Two Fumbles
The improvement this guy has shown since coming to WKU has been amazing. He has had some really good quarterback play over those year with Doughty and Mike White finishing in the top-10 the last two seasons, but then again, so did Goff his last two seasons. I think these two would be a perfect pair to grow together.
