Wochit News - Thin is in with some of the biggest members of the 49ers. Just ask guard Marcus Martin, who has lost about 10 pounds after playing at around 330 last year. He plans to drop several more pounds before the season starts. Martin, who entered high school at 360 pounds and was too heavy to play Pop Warner, has said he's in the best shape of his life. The reason for the reduction? The 2014 third-round pick indicated it's a mandate from head coach Jim Tomsula and offensive line coach Chris Foerster.
