When you see him in Portland it's pretty clear he has some NBA skills. I think this also is really good for organization morale - it's gotta be encouraging for Walsh, Drew, JD, etc., to see there's a path to the NBA through good play and improvement, with a dash of organizational need. Building on Hauser and Kornet and Pritchard (and, obviously, Tatum and Brown), that's some solid development success, which is going to be even more important in the big-tax era that's incoming.
Big picture, I think there's appetite in the market for more professional basketball - it's a good TV product, has good stats, players are recognizable, etc. I think the NBA is going a good job of blending in the women and G-League players to the All-Star weekend, increasing the two-way players, having the WNBA players doing NBA commentary, etc. It's good marketing to grow the industry of basketball.
I think they blow baseball out of the water in terms of growing their sport and capturing eyeballs.
