Last night on MLB Network, one of the guys said he believes the reason Bob Apodaca (the pitching coach for COL who just resigned) walked away is because he doesn't agree one bit with the 4 man, 75 pitch rotation. It absolutely kills these young kids confidence, and hinders their development greatly.
I think the Rockies announcers call it the "piggy back" pitching plan. Showed some stats last night that suggested it had worked...then said, "well, not tonight", after their RP gave up the three-run HR to Moore.
