Jameis Winston
There’s a world where the 2015 No. 1 overall pick is a productive quarterback for a playoff team. This is not that world until Winston solves his turnover issue. Giveaways would perhaps be the most likely reason the 49ers would move on from Garoppolo in the first place, and Winston is far worse in that category. While he led the league in passing yards with 5,109, he also led the league in interceptions with 30. That puts his career total at 88 in 72 games. Garoppolo is at 21 in 42 games after tossing 13 last season. Winston may put up bigger numbers, but his penchant for throwing the ball to the wrong team keeps him from being an upgrade for the 49ers.
