The 49ers don't appear very interested in Eagles quarterback Donovan McNabb. Matt Maiocco of the Press Democrat writes that San Francisco appears confident in Alex Smith as their starting quarterback in 2010. The 49ers will add a quarterback in the offseason, so they go to training camp with four players but the only question is whether they will add a draft pick or veteran to compete for a spot on the roster or if they sign an undrafted free agent as a "camp arm" who might be worth keeping around to develop.
