Isn't what the individual does to help win a playoff spot part of the individual's accomplishments? If all you have to do is focus on your numbers and winning the game, eating innings, ending a losing streak or whatever is necessary to help your team win are not, you approach the game differently. So does your manager with regard of how he uses you. It should not be all that matters but neither should pure analytics.
Zach Greinke once said he pitched to the analytics because that was what he thought would get the best results. He later said that was a mistake because it changed the way he pitched to produce results other than what was needed to win the game.
All that said, Skenes is an incredible pitcher having a great season and I think he deserving of front runner status as of today.
