He was a bit better as a Brewer and Dodger, but his Royals tenure wasn't that much worse than anything else.
The big difference in that W/L record is that KC was a tire fire while he was on that team and then afterwards he shuffled through a bunch of pretty good clubs. And Arizona.
Wins and Losses are stupid as a measure of player value, Buck/Pat. Figure it out already. And I know you can because I've seen you laud players for their record, and then for some other guys go "well, he's not getting the run support so that record is a little misleading" for others. So you know what the flaw is. You acknowledge that it exists. You just won't shift off your heels-dug-in insistence that Wins must be a valuable stat because like Herm Edwards once said, "you play to win the game"
