Too early to say Cleveland's new FO won't get it done, but they aren't off to a great start. I can't argue with how they went about it if they indeed trusted their scouting. If they felt like the QBs that were available weren't the answer then trust your scouting, deal the pick and build up the rest of your team.
Other teams have done it that way. Seattle kind of did it that way and brought Flynn and Wilson in as QBs and got lucky with Wilson, though with their defense they probably would have been good either way. Denver did it last year with basically a caretaker at QB, and is prepared to do it this year with Siemian, at least until Lynch is ready.
You do feel bad for their fanbase - man they are snakebit.
