No Wins/IP for a pennant chasing team do not matter because this is not a player + team award this is a player award. What the team does is irrelevant and doesn't matter. Skenes can't do anything when he is not pitching so why punish him for things that are not under his control but then award someone who did absolutely nothing for a team winning?
Lets say you have a pitcher who has a year of 1.50 ERA 15 wins 250 K's but his team only wins 50 games but another player who goes 3.50 ERA 15 wins 250 K's but his team wins 100 games. You are seriously going to say the better pitcher is the one who pitched at 3.50 ERA is the better pitcher because their team won more games? Lets take this even further what if the first pitcher pitched every single inning of their starts. Are you still going to say the other pitcher is the better pitcher and should win the Cy Young award because they are on a better team?
This is not a team award this is an individual award. You have to take the team results out of it which means you have to take out the wins. Team results mean absolutely nothing in an individual award, if this were the best pitching team award sure go ahead and use that information but this isn't that award.
