I wouldn't call Lamar much of a liability compared Jimmy G.
Jimmy G threw 8 passes because he is the liability....AKA Shannahan did not trust him to make throws. I'd rather have a QB you can trust to make plays.
The Niners would love to move off Jimmy G
You missed the Ravens-Titans game last year ? Ravens lost that game to Titans because of Lamar. Probably could say the same thing with Chargers game the year before.
