Pat Foley is basically the voice of the Chicago Blackhawks. Others have said just the same, and I have to agree. There are a few alternatives I could imagine, but generally speaking, Foley is it. He’s been around a long time and absolutely deserves his spot.
A good journalist is always present, but never obvious. If you read the news, you know someone had to write it, but it should never really be the journalist you hear in the article. The same goes for the broadcast booth.
We hear Foley. We know it’s him, but at the same time, it isn’t his personality that takes over the game.
