Cleveland Browns C Alex Mack opened extension talks with the team last week, according to executive vice president Sashi Brown. Brown said that if the team were to retain Mack, they would likely have to strike a deal before his March 4 opt-out clause date.

Footballguys View: Mack would see a lot of interest on the open market, but the Browns will do as much as they can to make this work. Mack is too valuable to the offensive line – and therefore the offense – to let him get away.
