There's something wrong with Nola, it's a good thing the Phillies have an opt out in 2023 ($4.5M buyout).
At $15M next year, he may be slightly overpriced.
He's no longer a top pitcher, maybe #3, more like a #4.
The velocity is there, but the command is off, especially the 2-seamer.
What made him exceptional was his ability to paint the corners, now he's more like VV, stretches where he looks dominant and innings where he looks bound for AAA ball.
His 4-seamer is hittable, and his curve and changeup have become more erratic.
When pitchers start having arm trouble, command tends to go before a falloff in velocity.
Of course, this may simply be "long hauler" syndrome.
