Well this will give us something to talk about during the bye week . . .
Seems like it will be pretty hard for Martin ever to return to the Dolphins given the way the locker room seems aligned against him. But the guy does have the potential to be a very good NFL tackle. He's a good run blocker, who's played pretty well on the right side. He was a left tackle in college and he's played there in the pros too, but so far has struggled against elite pass rushers. Because of this, the Dolphins brought in McKinnie to replace Martin at left tackle, but I believe they were planning to make him the starter on the right again.
With Vollmer hurt, the Pats arguably could use another tackle at least as a back up. Martin is certainly a reasonable second option and has the potential to someday be a quality starter. He's got some versatility, having played both the right and left sides (something not every tackle can do), and most of all he may be available cheap. My guess is the Dolphins are going to have to release him. He'll be subject to the waiver rules, I believe, but there's a better chance than usual that teams will pass on him because of the fear he won't fit in or will be a distraction. But Bill Belichick loves to take chances on these "value" players who other teams don't want because of concerns about personality. Dillon, Moss, even Lloyd are all guys who were thought of as potential locker room problems whom Belichick went for--in the process getting excellent value for the price.
The Pats' locker room seems to be a far more professional place than the Dolphins', and the team has a history of integrating players with reputations of being difficult without any significant problems. Martin might thrive in the more cerebral and businesslike atmosphere created by Belichick and Kraft, and if he lives up to his potential, the Pats could have a very decent young lineman for many years. I love Vollmer, but he's oft-injured, and the Pats have to be thinking ahead to his eventual replacement. Cannon could be that guy, but Martin might be worth a try if he's cheap.
Not saying that this will happen or even that it should, but it may be interesting to speculate about. It seems at least plausible from a coach who did not shy away from the potential media distraction Tim Tebow brought, and who has had no problem taking risks on players like Dillon and Moss when they became available at below market rates because of concerns about personality.
