The two guys from Tennessee are the highest ceiling WR's I see in this draft. Patterson is simply the most explosive player in the entire draft at any position for my eyes. He has the size, strength, build and determination to beat press coverage coupled with very good speed and phenomenal burst to create separation. His RAC ability is probably the best in the class. He has natural hands and good technique as a catcher, but you can tell he hasn't been coached at it as intensively for very long. Patterson is simply tailor made for the WCO. Bailey seems like one of many good small WR's.
Justin Hunter is an ideal fit in any offense, but he needs more strength, health and reps to develop into a Randy Moss/AJ Green style of WR. He's the best red zone threat WR in this draft, has deep speed, good RAC (despite being overshadowed by Patterson), willing and capable downfield blocker. But, he isn't strong enough and doesn't hold onto the ball in traffic well enough yet.
