I admit it's probably blinded by hope, but while everything you say is true, the problem is the raiders roster is awful. They have like two useful pieces out of 22. They don't have enough a qb, eb, wr, standout defender (outside crosby) or much on the line.
Right now they are among 13 teams with two loses or fewer and 10 of em need qbs. Someone is gonna be left out.
So by keeping crosby they are hoping to be one of the three teams to get high enough to get a qb. Or they are bringing in another crap vet and putting on the year again. Either way, next year is toast so now your heading into 2026 with still a need of talent but now you got crosby nearly 30 and on his last year. Each passing year his value goes down.
Now the other option is to trade crosby for 3 or 4 picks over the next two years, all probably top 100. So now you got the ammo to add more talent faster or use some combo of those picks with your own to move up to get that qb you've been searching for for thr last 50 years
While max might be homegrown keeping him, given all the circumstances might not be a good idea for the raiders.
