"Games take too long" They take 3 hours and they always have, what else are you wanting to spend your 1pm-4pm block on Sundays doing? Listening to your wife complain? Good grief.
The 5-10 minutes spent on the reviews pale in comparison to the TV-Commercial time outs, if you want to reduce the game times complain about that -- but that's not gonna change any time soon.
less reviews, they just fill with more commercials. They don't want a shorter air time that is less revenue it makes no sense.
The NHL who knows what they are thinking, their execs never been good at making the big bucks. Lets reduce the air time, that'll be great for sales! (lol)
