Just writing that out, it's quite obvious Cole is better by most every pitch, but there's a good Cole-esque pitcher hiding in Zack Wheeler somewhere. Mets also had him inexplicably throw as many sinkers as 4-seamers in 2019 despite one being vastly superior to the other.
The real danger with Wheeler is the injury risk, but I guess the positive there is he doesn't as many miles on his arm either.
