WR is deep this year for sure. At this time I would take Allen or Woods over Hunter, just because the highlights that I saw on Hunter were not that impressive. He didn't separate well, he went down immediately after initial contact, and he didn't look like he had any burst. Someone said that he had a knee injury last year, so that could be some of it.
Tavon Austin would be awesome to have, but I think they are looking more for a outside WR that has good hands, is taller so he can go get the ball, and has speed. That is why I would lean towards Allen myself, but things will change between now and the draft as we see pro days and stuff like that. I do believe they will land a playmaking WR in the 1st rd though.
