The San Francisco 49ers have three quarterbacks on their roster right now, along with Thad Lewis on injured reserve. When free agency arrives next March, it is possible, and even likely that all four players will be free agents. Colin Kaepernick is the only player signed beyond next season, but he has an option on 2017. If he performs well, he is likely to opt out of his now two-year deal. If he does not perform well, the 49ers are likely to release him.
It is safe to say the 49ers will need to invest in a quarterback during the 2017 NFL Draft.
