It's probably going to happen.
Young and Stroud look pretty similar to me. They fit on that Jimmy G, Derek Carr pocket QB game manager spectrum. Both are very smart for college QBs and are accurate. If their first read or second read is open, they can zip in a catchable ball. But if you cover their guys, or hit them with quick pressure, they won't punish you with a big play. They don't panic into mistakes - they'll throw it away or run out of bounds or something. But the league's best quarterbacks - Mahomes, Allen, Burrow, Lamar, Lawrence - all of them can turn a broken play into a huge gain.
The one exception that sticks with me is Stroud vs Georgia. Every other play for Ohio State was a broken play vs Georgia's incredible defense, and Stroud improvised for some huge gains. He balled out. In a game chock full of future NFL'ers, I honestly thought he was the best player on the field. If he carries that game into the pros, he is a franchise QB.
Richardson isn't even half as developed as a pocket QB. But he is hyper-athletic and thinks fast under pressure, and he generates huge plays off-schedule. That's sort of the acid test that separates elite QBs from the pack, and he has it. Some coach is going to think he can teach him to identify CB leverage before the snap, or drill his mechanics down until he can hit a slant route. There is a lot of risk, but the holes in his game are teachable, and his talent isn't.
