Been through there a million times, but didn't watch TV much. If so, there's TV's around most of the gates (seems like they're normally showing CNN, etc.). You might could also catch it in several of the eating establishments (Texas Stadium Grill, etc.). If you're just driving through, there's a place called Humperdinks in Arlington that has several TVs (off 360 not too far from Six Flags). Caught the UAT-UTK game there earlier this year on ESPN & they will change the channel for you if requested. That's really the only bar I've ever hung out at in the metroplex.
Edited to say, there's a bunch of places to eat down on I-20 (near intersection with 360) that ought to be carrying the games.
