No one expected Fitts to go much more than twice through the lineup, anyway... so "only going 2.1" is not that far off base. I thought going 3 full would be a good start for him.
I much imagine he was instructed to throw so many curveballs so he could set up Girado, who LIVES off his slider. Also, there is a difference between hitting a curveball and hitting a hanging curveball. I only remember one curveball he really hung bad... other than that, he was throwing pretty good curveballs.
Also, no one on here has said they want him to pitch because his powerpoint presentation. That is completely irrelevant. People want him to pitch because he's solid and has pretty good pitches. He's given us good starts and set up our relievers... which is what we want.
