The Raiders first big move of free agency came Tuesday when they agreed in principal to a deal with offensive lineman Kelechi Osemele.

As we wait for the team to announce the deal, Osemele took to Twitter to confirm his signing with the Raiders.

Perfect Fit — Kelechi Osemele (@KOsevendeuce) March 9, 2016

That skull emoji is rather commonly used on Twitter to represent the Raiders and Osemele does seem like a perfect fit for this team. He’s a bruiser at 6-foot-t, 330 pounds and his signing beefs up the offensive line and still creates flexibility. If the Raiders were to resign Donald Penn or end up with someone else to play left tackle, Osemele can easily slide into to one of the guard position. If not, he’s capable of filling that key left tackle spot.

The Raiders should announce these moves at some point, but for now it’s likely the focus is on Sean Smith and seeing if they can fortify that secondary.
