The only difference would be if both Purdy and Darnold got hurt and we've had so many injuries in this era that I wouldn't be surprised to see it happen. But make no mistake, Darnold and Trey weren't going to "save" a season really. Maybe a couple games. Brock is the only QB on the roster where I feel the team could win it all.
I'm just challenging the logic of these pro-Trey posts. If Darnold is too shyt to keep our season afloat, then what is Trey? In order for them to make sense they would have to claim that Darnold looked categorically worse than Trey in the preseason and they can't do that because it's not true, which is why they instead turn to Darnold's past production outside of this offense and Trey's hypothetical potential that we have no actual evidence of him being able to actualize. What we do have evidence of is this:
This is why Trey Lance is no longer a 49er. Putting this on tape in your third year in this system that you were once the starting QB of is very, very bad. Darnold has no tape in a 49ers uniform this bad. Backup QB is about a high floor. Darnold's was higher than Trey's. I was in favor of keeping Trey as QB3, because even if he can't run this offense well he at least has an arm.
I personally don't believe it's a wrap for our season if Darnold has to come in and spell Purdy for a bit. I think he can run this offense competently and we're far too talented on offense to let Sam Darnold sink us. All he would have to do is play point guard, not try and manufacture winning plays like he was doing with the Jets and Panthers. Granted, it's preseason, but so far as a 49ers he's shown he can do that. He can make the right read and deliver the ball. Purdy does it at a tier above Darnold, but I believe Darnold can complete 7 yard slants to wide open Deebo and 15 yard posts to wide open Kittle and hand off to CMC. This is not a difficult offense for a QB. Darnold has already made a few impressive throws here, the arm talent is there.
