In a keeper league if these guys know what you're doing I don't see him slipping too far. He's a dangerous option in an absurd vertical attack with the best receiver in the world playing next to him freeing him up for constant single coverage. He has a chance to be just beast and make your other WR's very expendable.
Titus Young, I assume? A lot of these guys will probably not explicitly pre-rank players and will rely on ESPN's pre-ranks (where Young is somewhere around 100, I believe). Dude could definitely be a beast, and he's a guy I'm going to target. That said, Burleson was supposed to get the same benefit the past two years, and he just didn't make it happen, so if I misjudge the market and miss Young it won't ruin my draft.
