People that focus on Cole's mistakes are missing the big picture of what Bob Cole offers.
Play by play broadcasting is very hard and its remarkable that he still does it so well. I mean try it for like 30 seconds in your own home with the sound off, im sure you'll be mostly saying "Subban gets the puck, Subban passes to Markov, Markov skates with it, now he shoots, and boom goes the dynamite." What a broadcaster does is add detail to each of these actions and Cole still does that very well, even if he occasionally gets the players wrong. He adds a lot of nuance still to descriptions. Plus the "oh babys!"and "it takes a funny hop!"
Have you ever talked with an 80 year old? Things slow down a lot. This isn't Vin Scully calling a lazy afternoon ball game.
