'It's no secret that pretty much everybody on the 49ers' roster that wasn't drafted in the first round over the past two seasons is available to any team that comes calling. Torrey Smith may not be an elite receiver, but he can be a productive one on a team that can get him the ball, especially deep. Buffalo lost a big weapon when Sammy Watkins went down hurt, and Smith would go a long way towards giving the Bills some of that deep weaponry back. Smith's average depth of target this season is 15.6 yards downfield, but he has caught just 43.3 percent of the balls thrown his way because of disastrous San Francisco QB play.'
