So, I've though about it a bit and I've come to an interesting conclusion: WN8 and WN7 are becoming relics of the past. These stat metrics are no longer the titans of determining a player's effectiveness, at least not as much as they used to be. WN8 can be easily padded in certain machines based on the machine's averages, and WN7 is simply a dinosaur that I doubt anyone really looks at anymore.
Is it possible that we need a new stat metric for measuring the performance of players? It's hard to say whether or not it's necessary at this stage of the game, but I feel like it has to be considered somewhat.
