C.J Beathard: Strong chance
Nick Mullens: Long shot (changed from weak chance)
Jack Heneghan: Long shot
While it’s a borderline valid question to ask if Mullens should have been the first man to relieve Jimmy Garoppolo when they played the Colts, but unless Beathard was ruled out with a foot sprain (he played) we were unlikely to see this happen.
While there is a small chance Mullens could be on the roster anyway, this is unlikely as the 49ers like to keep only two quarterbacks on the roster. Mullens’ only chance was to really impress against the Colts and then perform well in the final preseason game (starters are unlikely to play much if at all, giving backups more snaps).
Jack Heneghan has been a non-factor in camp, and probably won’t have any chance making the team. Maybe if Beathard and Mullens were both injured and the team didn’t like any of the free-agent quarterbacks on offer.
Beathard wasn’t great, but did take care of the ball going 7-of-8 and 83 yards against the Colts and was good enough to hold off any realistic chance of losing his backup role. Mullens performed decently overall, before a late turnover, and would be a good No. 3 option. But the 49ers are almost certain to keep only two quarterbacks, and thus I’ve bumped him down to the long-shot category.
