I don't think Leonard Taylor is at that level YET. But, somewhere between 5 (extreme low end) to 11 (the high end) interior DL are taken in R1-R3 every year. Guys like Leonard Taylor have gone around R3 for many years. That is provided he plays relatively well moving forward and tests at an NFL level. He needs to find his consistency, but he's produced enough and has some really nice splash highlights that show the potential...but he hasn't gotten consistent yet.
(IMO, this has been more of a preparation and motivation issue for Taylor...now that he is in money makin season, hopefully that untaps that consistency...its a big year for him)
