The lightning began a pod cast this summer - power play which is found on iTunes. I found the discussions with Espo and Dave to be real entertaining. I haven't listened to this week's broadcast with the assistant coaches yet.
I also listen to hockey central each day. They talk more about Canadian teams but do a pretty fair amount of league, and a surprising amount of lightning talk, too. I think it's because Doug MacLean is in Florida every weekend.
There is also the hockey news podcast, but that isn't uploaded in a timely manner and the hosts are typical hockey news jackasses.
