There's 308 events in the Summer Olympics and 102 in the Winter Olympics. So many sports WANT to be an Olympic sport that the IOC put a cap on the number of sports because 308 events is pushing it to the limits (or beyond).
Yet, the list of Summer Olympic sports includes a plethora of sports that are played INDOORS, that could easily just move to the Winter Olympics: Weight Lifting, Table Tennis, Karate, Judo, Taekwondo, Handball, Indoor Volleyball, Track Cycling, Badminton, Boxing, Fencing.
Winter requires FIVE ice arenas: Two for hockey, two for speed skating & figure skating, one for Curling. Very few bid on the Winter Olympics for that reason. You've gotta build ice arenas you really don't need to have the Winter Olympics.
Beijing is going to be a rare Olympic host that has had Summer and Winter Olympics. They have 13 indoor arenas they used for the Summer Olympics. They're going to use TWO of them for the Winter Olympics.
Move some Summer Indoor sports to the Winter, and move hockey to the Summer Olympics.
Cities HAVE plenty of 4,000 seat venues for small indoor sports. They don't have five ice arenas.
Los Angeles 2028 could ADD hockey to the Summer Olympics by using Staples and Honda Center for hockey, shifting some basketball to UCLA's Pauley Pavilion and USC's Galen Center, and shuffling the events slated for USC/UCLA to the smaller arenas at Long Beach, Fullerton, Irvine, Northridge or Cal State LA.
The issue isn't "Why didn't the NHL send its players to the Winter Olympics?" The issue should be "Why is Olympic Hockey played during the professional season when all the other pro sports are at the Olympics of their off-season?"
