Despite many commenters complaining about extended SD-only periods of NCAA Tournament action, we've gotten a lot of HD action on our CBS feed. As it turns out, the home team (University of Michigan) being NIT-bound might have guaranteed us more HDTV action than say, North Carolina residents. A CBS spokeswoman explained to The Mercury News that a lack of capacity causes the network to ensure the local market gets its preferred game, by only sending an SD feed. Otherwise, you'll get a "flex" feed, that switches to the best action, and in high definition. Next week, once some teams have been eliminated, there will be enough capacity to get every game, to every market in HD. CBS says it's "likely" their capabilities will change for next year, but if they don't, HDTV owners might be rooting against their alma mater next winter.
