Quinn Ewers met the Saints at the Combine [Mar 24: Saints hosted dinner with Ewers]

I'm of the mind set you bring in a rookie quarterback every year. At worse, a practice squadder. If you have an established stud and hit on one of those, use it as capital to acquire other needs, a la the old Ron Wolfe model from Green Bay. Remember him parlaying Hasselbeck, Aaron Brooks, Ty Detmer into extra draft picks.
I'd agree if there were any chance we'd ever play them, but we have too many holes to be drafting backup QBs. You can get one of those in free agency for league minimum. So far it seems like the idea is to roll with the veteran QB over a young guy that performed fairly well with a bad team in 6 games against playoff teams last year. I don't see a QB beyond the 2nd round that would beat out our current backups so there is no point in drafting them if we aren't going to play them.
