Is trade in the works between Ravens and Redskins?Don't be surprised if sometime before or shortly after the draft, the Ravens and Redskins start talking trade.Washington badly needs starting tackles (yes, plural), especially if the club starts zeroing in on a quarterback at the fourth overall pick. The Redskins regretted letting Maryland tackle Jared Gaither get away from them in the supplemental draft a few years back, when the Ravens plucked the starting left tackle in the fifth round. The Ravens will not give Gaither a contract extension this year, according to a league source, and he currently has a first-round tender.However, the Redskins' second-round pick (37th overall), is plenty close enough to the first round for the Ravens, according to sources, and if you throw in a fifth- or sixth-round pick as added incentive, that's a deal folks. Gaither is represented by Drew Rosenhaus, who has a very strong relationship with Redskins owner Daniel Snyder. He could play left or right tackle, and would be a massive upgrade over anything on Washington's roster.The Ravens are hesitant to give Gaither a long-term deal because he isn't always ultra-competitive and he tends to get hurt. They like him as a person, but he inspires some hesitation as a player. If he stayed in Baltimore and had a heck of a season and eased some of those concerns, he would get rewarded, but I have a strong sense it won't come to that.Maybe a team such as Dallas parts with its late first-round pick for Gaither -- though it's not as likely -- but the Redskins make a lot of sense here for many reasons. Any team with a high second-round pick in need of tackle help (the Lions, certainly), would have potential, and the Ravens will be ready to wheel and deal if interest picks up closer to the draft, as I suspect it will.
