This is a guy I would love to see in the teal and orange next year. I think if Dez Bryant and Eric Berry are gone at pick 12 the phins should trade down and try and get this young man. I know a lot of you want McClain, I'm just not as high on the guy as some around this site. I believe the only 2 players that fill the Dolphins' needs worthy of the 12th pick are stated above.
On to Arrelious. This guy is a beast at 6'2" and 220lbs. He is projected to run the 40 in the mid 4.4's. He has it all. Kiper said it best (not that I put too much stock into what he says) "he would be a top 15 talent with a better QB throwing him the ball." Mayock has him as the second best WR behind only Dez. Right now most mock drafts have him going in the second round. I can almost guarantee after a strong combine he gets bumped into the first.
With all that being said if Dez or Berry aren't there at 12, I say trade down and try to get this young man. The Dolphins would get their #1 receiver and another draft pick or two along the way. Here is a video for all of you who are unfamiliar with "Rejus".
