Sports ain't the only escape out here. Some areas are opening back up. Many others have opened up completely. Lots of people going back to work, and depending on where we are with the virus, kids will eventually go back to school. If sports is all it takes for you to ignore the protests, then you're not really invested in this social change anyway and it will show.
Sports is what started the whole lock down. Did you forget that it was the NBA suspending its season that triggered everything. Sports has an important place in American society. If the NBA players choose to protest in this fashion it will send shockwaves and make people continue to pay attention even with things opening back up.
