My source on this story is pretty reliable. According to Mike McGlynn's Twitter account, the free agent offensive tackle has agreed to a contract with the Indianapolis Colts.
McGlynn was drafted by the Philadelphia Eagles in the fourth round of the 2008 NFL Draft. At that time, current Colts G.M. Ryan Grigson was working in Philly's front office. Grigson seems to be making a point of bringing former-Eagles tackles into the Colts organization. He also traded with the Eagles for tackle Winston Justice. The Colts are also rumored to be looking into signing former-Eagles guard Evan Mathis.
McGlynn was released by the Eagles just prior to Week One of the 2011 season. He was claimed off waivers by the Bengals, where he played in seven games, started four. McGlynn played center at Philadelphia.
With McGlynn and Justice now on the roster, it's pretty obvious now that the Colts will move last year's starter at right tackle, Ben Ijalana, back to his more natural position of guard.
It will be interesting to see where the team plans to play McGlynn. The Colts have holes to fill at tackle and center, assuming Jeff Saturday does not re-sign or retires.
