Vastly.
Young- he's the prototype in everything except for size. Was a #1 recruit, 5 star, athletic, mobile, good enough arm, can make plays in or out of structure, with and without pressure, Heisman winner, has put up elite numbers, played well consistently in high profile games. He's done it all. He has it all except he may be only 5'10", 185lbs. Teams have seen what he can do, but can he do it at the NFL level?
Levis- he's the opposite in a lot of ways to Young. He has the prototypical size, 6'3", 230lbs. Has a HUGE arm. Is mobile enough. But he wasn't highly recruited, is in the SEC but hasn't played on the big stage due to being at Kentucky. He hasn't played with a ton of NFL talent, and it got worse from 2021 to 2022 when he lost a couple players to Day 2 in the NFL. Teams haven't seen what he can do when everything is perfect, but can he show it when you perfect his supporting cast?
Stroud- he's the perfect mix of both. Was highly recruited, athletic, good arm, has played in high profile games but hasn't really performed well in them until the Semis vs Georgia. He has been coddled at Ohio St, by them playing easy schedules, having thrown to at least 5 different 1st round WRs in 2 years, and he hasn't really performed until the GA game when things break down in the pocket. Teams have seen what he can do, but can he do it when he has easily the most talented team on the field?
