EARTH CITY, Mo. -- For those waiting for the St. Louis Rams to finally add an offensive lineman, they got it done Wednesday afternoon. But it's probably not one of the two or three you were expecting.

The Rams signed offensive tackle Garrett Reynolds on Wednesday with an eye toward adding some much needed depth on their line. Reynolds spent the 2014 season with the Detroit Lions after playing for the Atlanta Falcons his first four years in the league.

In coming to St. Louis, Reynolds will be reunited with offensive line coach Paul Boudreau, who coached Reynolds from 2009-11 in the same role in Atlanta. That familiarity almost certainly played a part in bringing Reynolds to St. Louis.

In five NFL seasons, Reynolds has appeared in 52 games with 27 starts, making starts at guard and tackle along the way. That versatility also makes the 6-foot-7, 305-pound Reynolds a fit for a Rams' line in need of depth.

While the Rams do have openings for starters at right tackle, one guard spot and center, it seems unlikely the Rams view Reynolds as the answer for one of those roles, though that that could change depending on how the rest of the offseason goes. For now, it's probably better to view Reynolds as a sort of replacement for Mike Person, the versatile lineman who departed for Atlanta in free agency last week.
