I think the real point of those four years of stats is that his good years and his bad years are actually not that far apart from each other. There are some tangible differences (more home runs, fewer Ks) this year but that 1.18 WHIP is actually the ninth-best in the league, and while his 4.19 FIP doesn't sound that great on paper it is 16th in the league, ahead of all the other Phillies starters not named Wheeler and just a bit below (the also struggling) Alcantara.
He is failing to be the ace or even #2 we always want him to be, but the idea that he's a #3 or #5 is a product of not knowing what #3 and #5s leaguewide actually look like (even his unimpressive regular ERA is 18th in the league). Unfortunately, the winning formula from last year of having two aces just isn't an option; if Nola isn't the Game 2 starter that's not ideal either, but patching it together is all they can really do.
Like the column I posted above says, all of that means Nola is probably still a good pitcher going forward, but whether it's luck or mechanics or the pitch clock, his performance won't necessarily change this year. Of course we've also seen him have great starts and signs of the "old" Nola (though not in a little while now).
Also like Hamels in 2009, thereâs at least a case to be made that Nola isnât actually this bad. His 1.19 WHIP is ninth in the National League among starters, and all of his advanced metrics â FIP, xFIP, SIERA, basically all of the acronyms â look significantly better than his actual ERA. But all that really says is that Nolaâs talent hasnât disappeared; itâll convince his suitors in free agency this winter that the pitcher is fully capable of bouncing back in 2024. It doesnât really matter for the Phillies now, if Nola continues to show no sign of possessing consistent ability to keep actual runs off the board.
