He did nothing with the Cubs....did he?
He should certainly get some credit for the WSs, but the core for the 1987 team wasn't his. More credit to him for the 1991 group....but I think you also have to consider that after he left, the place was a mess right? Maybe he did everything right nad the guy behind him failed, ....
.....but his 'big thing' was supposedly the ability to rebuild (or build, whatever) a system and I don't think there's any evidence he was any good at that.
If he was good at everything, we should see those results across all three teams, if he was good at one thing (rebuilding, winning, whatever) we should see those results across his opportunities.
His Cubs and Orioles days MAY indicate that some of his success in MIN wasn't some intentional act on his part.
I guess if you make the list because you have 2 WS on your resume, then he's in.
What's the W% of all of the teams he's GMed? Is that good enough to get you on the list?
TBH, I'm not well-versed enough in his Cubs and Twins days to say what he did and didn't do there, but if his thing is being a rebuilder, why are you grading him on immediate returns? If he walks into a 50-win team, he's not going to make them a 90-win team in a year. He has to handle guaranteed contracts to bad players; even if he just cuts them, they're still taking budget space. If his job is to lay the foundation for a winner, that means his W% is going to be in the tank already because he's working with bad teams.
Drafting and/or bringing in and/or developing Jones, Koji, Davis, Hardy, Tillman, Britton, Matusz, Wieters, etc. really doesn't do anything for you? How was that a joke? Because he couldn't make Tillman an ace in a year? Because Wieters wasn't Mike Trout? He could draft as well as anyone has in the history of the game and it would STILL take a few years for that to show up because players have to prove themselves with SOME MiLB time. MacPhail put the core of a winning team together, and I'm not sure how you can say otherwise.
