Seattle Seahawks: Edge Aidan Hubbard29 of 32AP PhotoThe Seattle Seahawks had one of the best defenses in the NFL last year, and the roster of the defending champions won't be an easy roster for an undrafted rookie to crack. But the Seahawks fielded that stout defense without a true star on the edge, and after the departure of Boye Mafe to Cincinnati, Seattle has an opening at the position—an opening that Josh Edwards of CBS Sports believes Aidan Hubbard might fill quite nicely:"Seattle lost Mafe via free agency and then gave Hubbard the largest practical guarantee ($267,500). Hubbard had at least six sacks in each of his past three seasons. He does a good job setting the edge and playing in pursuit down the line. There is not a lot of explosiveness or overwhelming physical characteristics, but there is some reliability in the run game."
