I never said Shoemaker has better stuff than Richards, nor has he put together a season like Richards had two years ago.
What I did say is that the way Shoemaker has pitched in the past couple months is far superior in terms of shut down, ace-like performances with a very good strikeouts to innings pitched ratio...something Richards has not been able to string together in a long time. Also, Shoemaker's rookie season was pretty fantastic too.
If you rule out a bad stretch last year and the opening to this season from Shoe, he's been a very good top of the rotation type pitcher.
You do not need to throw 98 MPH to be classified as an ACE. Max Scherzer in his 19 K performance this season was throwing 91-95 MPH, sitting mostly at 92-93 the entire game. It was his wipe out slider and pinpoint control that led to that dominating start -- something that GR too has not been able to do on a consistent basis. There's more times than not that Richards' high octane fastball has so much movement that he doesn't know how to locate it and he finds himself walking batters, hitting batters and throwing a ton of wild pitches, which also led to just 5-6 inning outings which tax the bullpen.
