"Pitching A to Z with Chris McCoy" review

I have this semi old DVD-CDrom set from Chris McCoy and Pitchsmarter.com (which isn’t there anymore) called Pitching A to Z. Its pretty good from what I see out of the whole thing (and its similar things that former Major League players have taught me while training). Anyone have any thoughts on why the drills are bad or good? Any ideas are welcome? I just think its cool for the work that was put into it.
