I won't disagree with you, but in the 90's they had some amazing stats relating to specific sports or players. They really did break it down. But that was also when they were giving equal treatment to NBA, NHL, MLB, NFL...hell even NASCAR. Then they realized that NCAA was MUCH more lucrative of a cash cow. That was in the day when ESPN2 was basically the "skateboarding" channel.
But yes, there is no substance now to their stats it seems like. Now it is "Lets see Lebron's stats when he has a 4 year old child in attendance" as opposed to relevant. However, NHL Network isn't any better.
