CAMP OBJECTIVES: Obtaining more explosive weapons to an offense that ranked 29th in passing yards during last year's breakthrough 13-3 campaign was the offseason onus of the 49ers' front office, and getting those newcomers ready to go when the real games start will be the top priority of camp. The most notable acquisition was that of seven-time Pro Bowl wide receiver Randy Moss, though the mercurial 35-year-old must prove he can still be an impact performer after sitting all of of last season and putting together a rather unproductive 2010. Giants Super Bowl XLVI hero Mario Manningham and rookie first-round pick A.J. Jenkins will also attempt to earn prominent roles on a totally revamped receiver cast, while former University of Oregon speedster LaMichael James (2nd Round) has an opportunity to make a mark as a change-of- pace alternative to workhorse running back Frank Gore. Another interesting preseason battle will come at quarterback, where ex-Buccaneer Josh Johnson and 2011 second-rounder Colin Kaepernick will compete to be the No. 2 behind entrenched starter Alex Smith. The Niners have to replace only one regular, right guard Adam Snyder, from last year's NFC West championship squad, with third-year man Alex Boone entering camp as the favorite to step in.
