Raiders early favorites to land Ravens free agent Kelechi Osemele

Since the season ended, the Baltimore Ravens weren't expected to retain offensive lineman Kelechi Osemele. With free agency set to kick off Wednesday, Osemele's exit appears a done deal.

The Oakland Raiders are considered the front-runners to sign Osemele, sources told ESPN's Adam Caplan and FoxSports' Mike Garafolo. The deal could exceed $10 million per season, which would rank Osemele among the 10 highest paid offensive linemen in the NFL.

The Minnesota Vikings are also a strong possibility for Osemele, according to the NFL Network's Rand Getlin.

Osemele is the Ravens' top free agent this year, and he has ranked as high as No. 3 among all free agents in the league. The Ravens made what they called an "aggressive" offer to Osemele, but it was expected that teams with more cap room would outbid them. The Raiders currently have the second-most cap room in the league.

A second-round pick in 2012, Osemele excelled with the Ravens because of his toughness and versatility. A mauling run-blocker, he has started at right tackle, left guard and left tackle for Baltimore.

If Osemele goes elsewhere, the Ravens likely will replace him at left guard with either John Urschel or Ryan Jensen. The bigger decision is at left tackle, where disappointing Eugene Monroe is scheduled to make $6.5 million this season, the second-highest base salary on the Ravens. Baltimore would create $2.1 million in cap space by cutting Monroe.
