I have no problem with much in terms of analytics, but I don't see how analytics are really entering into the DH discussion. I agree that it is problematic that benches get burned by pinch-hitting, but that has more to do with the changing nature of roster construction than it does with analytics. I grew up in an era when 10-man pitching staffs were the norm (of course, the average fastball velocity was below 90 mph) and with 7-man benches, most teams carried a pinch-hitting specialist (Smokey Burgess, Manny Mota, etc.). That has changed and it's not all bad.
But I think forcing pitchers to face more than one guy (I like Dirk Piggler's suggestions) is a good move. I just hope Tony Fossas doesn't hunt me down for writing this. For those of you unfamiliar with Tony, in 12 major league seasons (11 full seasons), his IP only exceeded his number of appearances twice (and one of those seasons had a total of 5 appearances and 5.2 IP).
For the record, I don't have that much of an issue with the universal DH and my comments about bunting were related more to no one knows how to bunt anymore divorced from any strategic implications of its use.
