xc - a very good option is to get a slingbox and set it up at a family member or close friend's house in TX. Pick someone who A) has more cable boxes than they know what to do with, B) has a good sports plan, and C) has a very good internet connection (upload speed on their end is the biggest quality limitation). Slingbox is good because it's only an up-front cost; there's no recurring charges after you buy the device (and apps, if you want/need them).
My slingbox is at my father-in-law's house, and I've used at for a couple football and basketball games each season. Quality isn't as good as ESPN3 feeds, but it's acceptable for meeting your "fix." I only have the SD slingbox. Their HD version supposedly works great, but again, the upload speed on the other end is the biggest limiting factor to quality. Perhaps the best feature of slingbox is the slingbox mobile app where the resolution actually looks really great on a phone and streams very well with a typical 3G signal.
My FIL's cable package is tremendous, AT&T U-Verse. He actually has more west-coast regional FSN's than I do and I live in CA, so maybe if you're moving to an area with U-Verse, they'd be a good option if you don't want to do the slingbox thing.
