The Dallas Cowboys haven’t made many moves in NFL free agency this offseason, but the ones they have made could be vital to the team’s success next season. This could be especially true concerning their latest rumored acquisition, offensive lineman Marcus Martin.

Martin played for the Cleveland Browns last season. He was drafted in the third round in 2014 by the San Francisco 49ers out of USC.

The Cowboys have become known for their offensive line in recent years. But last year, the line wasn’t nearly as good as fans have come to expect. Losing two starters during the offseason (free agency and retirement), hurt. But they also struggled to deal with Tyron Smith’s back issues as well.

So, while they haven’t made any big splashes in free agency, they have been quietly making deals for quality players that fit some of their more pressing needs. The team recently signed tackle Corey Fleming away from the New England Patriots as well. Financial details of the contract have yet to be released.

Martin, like Flemming, is not expected to be a starter next season. But the Cowboys want to make sure that the offense doesn’t suffer in case one of the starters goes down for an extended period of time—like when Smith missed time with back issues last season.

There is a strong chance the Cowboys are going to move La’el Collins back to guard. But if they can’t find someone else to start at tackle, Martin could have a shot. But the Cowboys are also expected to address the guard position in the draft.
