I don't know about awful. It will depend on where they all land.
If Rosen/Darnold lands on the Giants they should have a relatively good career and the easiest job between the two (the other will be in cleveland). If Rosen lands on the Browns he'll be a bust, if Darnold lands there it's a toss up because that first year with Hue is gonna be TRASH but after that anything can happen.
Lamar Jackson will shine if he goes somewhere where they are either okay with him sitting a year or dont ask him to do much ala Wentz. If the Dolphins/Jets pick him hell probably bust or get injured.
I think Allen is a bust anywhere but the Jags as far as teams that have QB as a need. Mayfield is a complete toss up.
Perhaps I'm wrong but this is how I see it. Darnold still hasn't declared because of this, he knows where he gets drafted is going to be everything.
