The problem to me is the "interesting" part of that statement. The only healthy SP we have firing bullets at the moment is Wiggins, while it seems like the remainder of the guys who are successfully pitching are RHPs who work in the low 90s and seem to rely a lot on arm angles and deception.
Don't get me wrong, it's great that these guys are bolstering the depth in this system, but when the 90th percentile outcome for your career is Colin Rea, well, yeah.
