There is an issue w/ the great Orioles teams of the late-60s / early-70s, but IMO it's with their defense rather than pitching. To the degree that the O's got crappy cards,
Gold Glovers Mark Belanger and Dave Johnson should both be rated "1" for range. As an Orioles fan, this has always irked me!
Those teams were somewhat over-rated as a pitching team. Yes, they had great starting pitchers, but that team was great at EVERYTHING. Their strength was hitting and especially DEFENSE. The 1969 Orioles were one of the greatest defensive team ever and several other years (esp. 1973) were close. Check their defensive stats on Baseball-reference.com.
Several years ago, I read an article on
Baseball Prospectus by Jay Jaffe - he was discussing all-time great pitchers and commented that
Jim Palmer got more help from his defense than any pitcher in the history of major league baseball.
