In most areas, yes.
In some bandwidth starved areas, CBS Sports Network HD isn't found in HD or in SD in any package. Lewistown, PA, Mt. Union, PA and Frostburg, MD are 3 systems I know of that do not carry the channel in any form.
You'll have to consult with your local channel lineup to make sure. SD and HD channel numbers will vary depending on location.
