"We had an awesome run with Jimmy, it was great," Shanahan said, via 49ers Web Zone. "But when you bring in a salary cap and things like that, there are so many tough decisions that you have to make and we made [that decision] a year ago. And we got to here and I was so happy [with] how Jimmy played last year, that he took us almost to the Super Bowl, got healthy, [and] guys around him played real well around him. But this is something that we did last year knowing where we wanted to go with this franchise and how you balance out a salary cap, how you balance out a roster, and Jimmy gave Trey a year that I thought he needed just to get used to this league, get his feet wet a little bit."

Shanahan reiterated the team's outlook at the quarterback position during Tuesday's press conference, telling reporters, "We have moved on to Trey."
