Jimmy Williams, 22, was a sixth-round draft choice of the Bills this spring, the 196th player selected overall. He was the only player drafted by the Bills who did not make the roster, but the club attempted to retain his rights by signing him to the practice squad.
He declined the Bills’ offer to sign instead with the 49ers PS, in part because of the presence of former Vanderbilt teammate Jamie Winborn, a LB with the 49ers. The two, both represented by agent Terry Bolar, now are roommates.
