Nothing inherently wrong with it…just consider this:
1. Totally not tzinus women everywhere.
2. Complete waste of time
3. Complete waste of money
4. If you really think about it (and I mean NOOOOO offence to anyone) but the core reason of why people like sports is because they want to be part of a winning team. Why do people need to feel that? Because they’re losers in the parts of their life where they feel they should be winners. For example, you know you need to keep shabbos but you don’t. And if your team lost, well no worries at least there are thousands of others who feel let down so you’re “not alone”. It’s like taking a test in school, when you see you failed you feel horrible. But when you find out that everyone else failed you don’t feel as bad. But the reality is that you still failed….just because everyone else did shouldn’t make you feel better.
