Shaq won one MVP in "the shaq era", so I am not sure why it's so hard to fathom the idea of someone else winning one. (Steve Nash won 2!)
Giannis came to the NBA as a 19 year old kid who wasn't ready to play from day 1, Grant Hill played 4 years for the best college team in the country, I'm not surprised he was better in their respective rookie years. Hill was 22 for his rookie year, if you want to take Giannis from his age 22 season, then that would just be the last 4 seasons, where's he made the AS team every year, second team all NBA twice, and whenever they vote on the awards for this year will have made all NBA first team twice with 2 MVPs, plus 2 first team all defense and maybe even a defensive POY. There's just no comparison between Hill/Penny and Giannis. Those guys were very good/great players who could've gotten even better. Giannis is the guy in the league right now.
His per 36 averages the last 2 years is something like 32-15-7. How exactly is Shaq taking MVP's from him?
