Based off of what? Rocker is throwing as hard with more consistency and less variance, and he doesn't possess obvious injury concerns unlike Hankins. His curveball is also better than any secondary pitch that Hankins is currently throwing, considering that he scrapped the slider (there seems to be legitimate concern that the pitch is hurting his arm, hence why he's not throwing it and has replaced it with a fringy curveball). I mean, the difference between the two wasn't that great even back when Hankins was getting top 1-3 type hype, except now you have one guy who's stayed healthy and has pitched as well as he did last summer, while the other guy got hurt and has had velocity all over the place while also scrapping his best breaking ball. Seems like a no-brainer to me.
