Here in Canada, our ESPN equivalent is TSN (The Sports Network) except with 100000% more hockey and 100000% less college sports. There are specific hockey dedicated shows and the regular sports highlight shows have hockey segments. One of these segments, which also appears during game broadcasts at intermission, is Insider Trading.
Insider Trading is basically a host with 2-3 hockey experts/insiders. Today they had Darren Dreger, Pierre LeBrun, and Bob McKenzie. Most people would say McKenzie is the most distinguished and he has been around a while and is definitely a legend in hockey media. When he breaks a rumour or trade, you know it's legit.
