Of course I'll be watching. And I'll be eating and drinking, too. Wouldn't miss it.
And even though I'm not a Chiefs or Eagles fan, I do feel like I'm witnessing greatness when I see Mahomes and Barkley play. Felt the same way about Tom Brady, Jerry Rice, etc. I hope, for your sake, that you have the ability to appreciate that even if you don't have a rooting interest.
The same way I loved the Yankees-Dodgers world series this past season even though I despise both teams. A walk-off grand slam in game one, and then the Dodgers coming back from a 5-0 deficit in game 5 by scoring 5 runs in one inning assisted by error after error by the Yankees. What a wild win for the Dodgers and epic failure for the Yankees! If you sat that out, you missed a classic.
Sometimes you have to put aside your chauvinism for your team and your hatred for other teams (and Taylor Swift) and your conspiracy theories and your betting interests and just enjoy the game as a fan of the sport. You might even enjoy it more if your team's not in it because it isn't as stressful!
