The Raiders have added a youthful edge-rushing prospect.
A second-year player from Idaho, the 23-year-old Mayowa played two regular season games for Seattle in 2013. He notched eight tackles and a half-sack in the 2014 exhibition slate for the Seahawks, including three tackles in the preseason finale at Oakland.
While Mayowa departs the defending Super Bowl champions, he could have an interesting opportunity in Oakland, where he could rotate in behind starting ends LaMarr Woodley and Justin Tuck, two of the more accomplished pass rushers of their generation. Mayowa (6-3, 252) could also conceivably be tried at strong-side linebacker.
