Starters are a mix of fan, media, and player votes (50/25/25 weights). Coaches vote for the reserves. I suspect Gobert probably gets in as a reserve. He's probably the #6 "frontcourt" player in the West this year and there are 6 spots guaranteed for "frontcourt" players. Players he's probably behind are Anthony Davis, LeBron James, Kevin Durant, Nikola Jokic, and Paul George. Others he'd be in competition w/ for the 6th frontcourt spot (and there could even be 7 or 8 taken depending on who the 11th and 12th spots go to) include Towns, Aldridge, Capela, Doncic, and a few other fringe candidates. I think Gobert gets in ahead of any of them if it's the coaches voting.
