on the ball: I don’t think so. The Chiluk is obvious. The Gemara has very harsh words for those who attend stadiums because that’s what attending a stadium entailed back then. It’s clearly not what it entails now. You are the one reading something into Rashi that isn’t obvious (that he is including even something that didn’t exist back in his time). It could be that Chazal would have included today’s sports in that. But the Chiluk to say that they would not be included is obviously there. It didn’t exist, so we honestly have no idea if Chazal included it or not. Saying that Rashi clearly includes it is just as not-Muchrach as saying he clearly excludes it.
