Former 49ers quarterback Seneca Wallace says the only reason San Francisco signed him this preseason was to squeeze fellow backup quarterback Colt McCoy to get a pay cut. “I’ve been around this game long enough where I can see what’s going on” Wallace told the Des Moines Register “and I realized right away the reason they brought me here was to get Colt to take a pay cut.” Wallace who left the 49ers amid reports that he was retiring said that in reality he just didn’t think San Francisco was the right place for him.
