I hear that comcast also f* with other cable co over TCN comcast network Philly that has CSN + / over flow games on it and RCN cable just misses out on some of the games.
It's good that they only own 20% of csn Chicago or that may of been cable / comcast only as well and the other guys got CSN + games that where on CLTV (long time comcast only) and mojo HD (cable only) later TLN and comcast network Chicago 101 for CSN + 2
