Watching a game on TV could never compare to the actual experience of being there. Even curling seems exciting when you're watching in person (I can't personally attest to that, but humor me here). Cough up a little cash, and splurge on taking her to actual game, and we guarantee she'll get caught up in the excitement and be screaming in the stands, no matter where your seats are.
If you have money to blow, you could even use the game as an excuse to take an impromptu weekend trip to Boston or Miami together. Take a cue from Kanye and use the game as opportunity to show her some action on and off the court.
