Meh, not everyone follows the Raptors. And I believe it is a new term, at least I don't think I've heard it before. I don't care too much about the NBA (at least until the playoffs), as long as this doesn't "catch on" in the NHL, I'll be happy.
Oh it's coming. Give it time. The amount of data that's out there.
What are the numbers of player X in back to back games with travel? Or in the games after playing 3 in 4 days or after playing 4 in 6. Remember last year after the California trip they played in St.Louis on the way home and got slaughtered? If a couple people took the 3rd game in California off.... Maybe they win or at least compete. I think they played Col/Ari/LV 3 in 4 nights in that trip too.
If significant trends emerge that show dips in production It's going to happen.
Who was the first person to figure out goalies shouldn't play back to backs
Remember when goalies were expected to play 75 games? No one gave a bleep who the backup was. How much does this board argue about Sparks vs McBackup.
If you're of a certain age remember when the concept of a Bullpen in baseball didn't exist?
Now look at it, 6 innings from a starting pitcher is a good start..... The stats people all figured out that the 3rd time through the order the performance of a pitcher dropped significantly.
