You act like he was a bad pitcher in 2015.
There are many pitchers who are MEH or barely above average, until they learn the act of pitching, or come up with their "out" pitch.
Jake Arrieta comes to mind, Curt Schilling, etc.
As a lefty, and breathing, with decent stats, yes, I would take a flyer on him.
But, we can agree to disagree, no worries, its all good.
