Marshawn Lynch has looked quick in and out of his cuts in the OTA setting thus far, which is even more impressive after he informed the media that he?s added more than 10 pounds of muscle to his frame. ?I bulked up to about 230 and put some mass on,? Lynch said. ?We?ll see how that?s going to work. I haven?t lost a step. I feel pretty much the same.? The Bills feature back was listed at 215 pounds last season, so 15 pounds is a significant gain even for a well put together back like Lynch. But even he?s not sure he?ll be able to maintain it coming out of training camp in August. ?Probably during the season it?ll be pretty hot so it probably won?t stay on,? said Lynch. ?I don?t know if you put on weight to add years to your career, but it was something different for me.?
