At least you can watch it. It showed up late last month on KFPB-LD channel 50.6 in Phoenix, replacing a shopping channel. KFPB is by far the worst station in the Valley, and Stadium is one of the worst subchannels they air, featuring a fuzzy picture and a very low volume level with frequent audio dropouts. Unwatchable.
As to its content, if is not bad. It is a low-rent version of ESPN, et al. Has deals with several not-quite college leagues and some other stuff Does a sports talk show that is pretty good in the late afternoon.
