What we have to consider is this:
Joe Douglas did not draft Sam Darnold. There was never a real plan in place to build around him, unfortunately. Maccagnan moved up in the draft for a QB and did not have a plan after that.
Darnold either steps up this year and proves he belongs and plays us out of that #1 pick, or we are the worst team in the NFL with him at QB and it'd be time to move on because you can't pass on Trevor Lawrence.
With all that said, this team is in a much better place now than it was in 2018 when we took Sam. Douglas appears to have a plan and he has cash and draft capital to use to help our QB (whoever that may be).
It's not like we'd take Lawrence and that's the only pick we have. We still have 3 other first rounds in 2021 and 2022 and loads of cap space.
We can take Trevor Lawrence AND a WR late in the 1st round AND a gord in the 2nd or 3rd round AND sign a receiver.
If Sam Darnold is as good as we think he will be, he should be able to pull out a couple wins for us and get us out of the #1 pick. It's possible the rest of the team is so hopeless that can't happen, but most teams who end up with the #1 pick have a QB injury or QB ineptitude.
I think a big reason why Douglas took the job was because Sam Darnold was in place. I don't think he wants to replace Sam Darnold, even if he didn't draft him. However, we need to start making decisions on Darnold's contract starting next offseason, and if we get the #1 pick, that means Darnold is likely replaceable.
