Jason Bay is also a vulnerable hitter who shouldn't be our #4 hitter, neither should Drew.
Again, the "context" is that Dunn is a VERY vulnerable hitter, do you argue otherwise?
He gets a lot of cheap homers and RBI's, but do you really want Dunn in a crucial spot K'ing like there's no tomorrow in front of above average pitching? Suit yourself.
Matt Holliday's probably a better #3 or #4 option than Bay or Dunn.
But hey, keep putting up your charties, logic (and his K rate) would dictate Adam Dunn is more a complimentary piece than a #4 bat.
Not to mention, he's under contract for next year, so he's not even our "best bet" because we'd have to trade for him anyway, champ.
