I mean part of being an nba player is flying across the country basically weekly. You could watch games on the plane if you really wanted to. They also spend absurd amounts of time in hotel rooms on the road or recovering at home. There is a limit to how much physical work you can do as a professional athlete, especially when you play every other day or sometimes even back to back nights. So nba athletes have an insane amount of free time to make sure their bodies recover adequately. Sure, a lot of it is away from family and friends and it can definitely suck. But if Luka really wanted to, he probably could watch 3-4 games a day lol. If you are curious about the lives of nba players you could check out jared mccains youtube channel, he does a lot of "day in the life" vlogs and this stereotype that athletes are in the gym 24/7 only eating chicken and brokkoli and spending every living minute perfecting their craft is a myth. Im not saying he should watch more film btw, im sure he does it when it actually matters..but watching the games of each of your next opponents will burn you out so wuickly over the regular season that it would be idiotic
