It’s a lot of the things you listed (defense, playmaking, motivation, etc)—the
same things that have always mattered in basketball. My point is that double-digit stats isn’t a great metric.
One player shouldn’t (and can’t) do everything. Donovan is getting better evenly year at play making, but when Mike Conley is on your team, part of being a great player is letting him be more involved in play making. When Rudy Gobert is on your team, you utilize that talent. Becoming a great player isn’t about maximizing your usage or shining the spotlight, it’s about maximizing what your team can do.
Go back to Allgiers 80 yd TD against Boise St. Who “made” that play? Was it just Tyler? Of course not. Every player on the field contributed. Even Zach had a bigger impact than “just” handing it off. His influence bent the defense and created the opportunity.
Anyway. I don’t mean to pick a fight. Just pointing out that influence is measured in countless ways beyond traditional stats and I believe Donovan does that (almost) as well as anyone in the league right now that isn’t named Lebron.
