If the Broncos are to stay alive in the AFC playoff chase, they will need to do so with their backup quarterback. Starter Teddy Bridgewater is still dealing with a concussion, so Drew Lock is expected to start (Twitter link via NFL Network’s Ian Rapoport). 
Bridgewater was carted off the field late in the third quarter of the Broncos’ 15-10 loss to the Bengals in Week 15. That left Lock to start last week against the Raiders, a game that ended in another low-scoring defeat and dropped Denver to 7-8 on the season.
A second-round pick in 2019, Lock holds a career record of 8-11, a QB rating of 78.2 and a touchdown-to-interception ratio of 24:20. The team’s offense has generally sputtered in the passing game with him under center, as Lock has recorded a completion percentage of 59.2% and an average of 6.6 yards per attempt.
With Lock starting, look for a heavy dose of both Melvin Gordon and Javonte Williams in the run game. This would especially make sense considering Denver travels to Los Angeles to play the Chargers on Sunday, a team allowing over 140 rushing yards per game this season, which ranks fourth-worst in the league. Brett Rypien would likely dress as the backup if Bridgewater is unable to suit up.
Let him start the remainder of the season and see if he’s someone worth keeping.
Rookie deal so they are definitely keeping him next year. I think they know what they got in him. He is a backup in the league that won’t challenge for starts
Probably true. Back ups tend to be guys who aren’t physically talented, but can absorb a playbook and understand concepts. Idk if Lock is that guy, but at least he has experience in the system
So you’d say he’s a Lock at a career backup?
Fangio and Shurmur don’t like Lock, thus Bridgewater must still be seeing double. As for the game plan, don’t expect anything that makes sense, as Shurmur hasn’t had a sensible offensive game plan all season.
Lock has had one or two good games and the rest is history. He will never be worth keeping. He’s too erratic to even be a backup in my opinion.
The thing that gets me watching Lock is that he doesn’t seem to ever learn from his experience. He’s still young, admittedly, but there doesn’t ever seem to be any cognizance of when to throw away, when to give up on a play, not to throw off his back foot or across the field, etc.
I get that Denver hasn’t had an offensive staff capable of developing a quarterback the last few years, but Lock just doesn’t seem to progress at all. He’s one of the few quarterbacks that seem to not have much of a role as a backup either, unless he can figure out how to play as a veteran and stop making rookie mistakes. If he does, then yes, he’s worth keeping. If not, I’m not sure that he is.
Agreed. Agreed. Agreed.
