He pretty much is all you can hope for out of a 5th starter at the moment except for the low innings total (60 IP over 15 starts, so about 4ip/start) but that could be a symptom of him still needing to stretch back out to starting full-time.
Otherwise he's given the team a 4.33 ERA, 4.44 FIP, 1.33 WHIP, and an opposing batting average of .222 while he strikes out about a quarter of the batters he faces, walks just under 12%, and his HR/FB of 12.5% is 3rd among this year's starters, trailing only Bassitt and Gausman.
If this is a starting point, it's a decent one. If he doesn't improve on anything next year except being able to log more innings then that's a serviceable back of the rotation guy or 1st man up. If he can find just a touch more consistency then he's an easy late piece in the rotation behind Gausman, Berrios, Francis, and hopefully Bassitt if he can get his 2023 groove back.
And if he can't get his stamina up to become a full-time starter, then at least he's got the makings of a nice bulk-innings guy for days where there are starter meltdowns or we need a bullpen outing.
I'm not really worried about him at all. Bassitt is probably the more worrisome starter just because he was expected to be a middle-of -the rotation guy and while he does provide that when he's one, he's had more meltdowns this season than he did last and he doesn't seem to be able to dig his way out of them mid-game at all. Fancy stats suggest that last year was an aberration and he probably shouldn't be counted on to be that good, but he still has to get his walks under control (it's the highest walk rate he's posted since 2018)
