Per PFF:
10. Stefen Wisniewski, C (72.5)
2015 team: Jacksonville Jaguars
Wisniewski is going to hit free agency for the second year in a row after signing a one-year contract with the Jaguars last spring. He performed better than his last season in Oakland, but this year was still a bit below his best years in 2012 and 2013. Pass protection is his strength, and he’s graded positively in four of his five seasons as a pro. Wisniewski is not an elite center, but he is one of just 13 centers who had an above-average overall grade in 2015 out of 40 qualifying players. Wisniewski has also been extremely reliable throughout his career, missing just 19 snaps over five years.
