I would say going from the 1st or 2nd most valuable transfer in all of college football, to being in courtrooms and rehab, and likely declaring for the supplemental draft (with a small hope of being drafted in a later round) means he has probably "learned his lesson". I do agree some sort of punishment is warranted, but I would be more lenient than most here and suggest he should get a suspension.
Sorsby's side has weak arguments: "Players wont seek help for addiction if the NCAA seeks the maximum penalty for Sorsby" or "It's not his fault because it's a health issue and we shouldnt penalize someone for a health issue". But, I also think that it's an equally weak argument to say: "If Sorsby is not banned for life, the entire game will lose its integrity and players will have an incentive to throw games on purpose and gamble on themselves."
The biggest indictment of Sorsby I have seen is that he bet against his QB while at Indiana, while having insider knowledge from practices, training, etc. While that's obviously inexcusable, and definitely illegal, there is still a meaningful gap between what Sorsby did and deliberately throwing a game, and that gap is why to me a ban is a disproportionate response.
My bigger issue is why gambling on college sports is legal at all, while we act surprised and appalled when a 21-year-old athlete develops a gambling problem. You can't watch sports nowadays without being bombarded by DraftKings and FanDuel ads, odds overlays, and celebrity endorsements making it all look consequence-free. We're in the middle of a documented gambling epidemic among young men, and the industry's response has been to lean further into it. I've seen it wreck people close to me, both younger and older.
