I think Edmonds COULD keep it going for a couple more seasons. Gator993's team has never done worse than 94 wins and is off to a 15-8 start, Ant013's team has never done worse than 88 wins and is also off to a 15-8 start, he's got a WS ring in Pete Rose. Polley070's team is a consistant 90+ win team as well with no WS ring (though he's got one from Moonlight Graham), and HuskyBoy's team usually lands in the 90's as well yet doesn't have a WS ring. After many seasons of rebuilding a decimated franchise Bimininole has a young team that should win 90+ for several seasons to come. I could see any of those 5 winning the next couple WS, and there are 3-4 other teams that are young wild card contenders currently that could pull an upset too.
On the other hand... mfkidd, darrenpv, blitz and axtell are all off to nice starts and always have competitive teams, and spudley and phillies26 I believe both have good teams as well but are hovering around .500 in hard divisions right now. My team is in rebuild mode but good enough that with some luck I could sneak into the playoffs and with more luck win another WS. That's a lot of luck though, and I'm really the only former WS winner that doesn't have a decent chance at winning this season.
