Now if you’re expecting a huge season from Manningham, pump the brakes a bit. The 49ers will continue to be a run-based offense, and Manningham’s numbers should be what you’ve come to expect in recent seasons — if they are even that good. Manningham would have had a chance for some bigger numbers if Manning had signed with the team, but not so much with Smith, Colin Kaepernick or any other quarterback the 49ers might turn to.
