Brohm had some fans. Claussen people were frankly dismissive of. Same with Quinn. Barkley was a joke too. Fans might have liked those guys but no analysts or former scouts did I can recall. Bridge would be the biggest disconnect between current NFLers and past ones I've ever seen.
I think you're using a little bit of hindsight to say all the players that didn't turn out to be good weren't very highly thought of in the first place. Don't forget a week before the 2011 draft Mel Kiper said "If Jimmy Clausen is not a successful quarterback in the NFL, I'm done. That's it. I'm out."
We all know too many QBs get overdrafted. It's extremely rare a QB gets underdrafted. It's possible this is all smoke and Bridgewater will go #3 overall to Jacksonville. But it's very possible if he drops, there's a good reason.
