OK, so, in tiger2022's defense, I do believe many people, including in the baseball media, are expecting (a step up from "hoping") that Verlander will deliver a solid WAR-positive 30+ starts for the Tigers. And yes, that could happen. He did have a solid Verlander-like final two months last season. he placed 14th of 54 qualifiers in ERA- and FIP- In August and September, although he did place 35th in xFIP, which is a reddish-pink flag. So, he wasn't super dominant, and his results were a bit lucky.
Stick around long enough, and every player will fall off the cliff eventually in a career-ending way. The chances that happens to Verlander in 2026 are fairly high.
Flip side, Verlander is already a freak of nature and he could also potentially have a whole year that is close to what he did last August and September, which could make him a solidly mid-rotation guy. Anything better than that would probably be into the upper-90th percentile of expected outcomes.
