49ers general manager Trent Baalke says the team's quarterback of the future is not on their current roster. Baalke will explore the draft, a trade or free agency to upgrade at the position. "Is the quarterback of the future on this roster? I think it's obvious that he isn't at this point, but things could change and they will change through one of those three vehicles," Baalke said in a radio interview with Mike Florio of NBC Sports. Former top pick Alex Smith is a free agent.
