Interesting question. You'd trade the 91 Series for 10 years of better records in the 90s and a couple division titles? Not saying this is wrong, just interesting.
Basically this question is the Royals, right? 1 series win, 1 series loss, amidst a couple decades of total ineptitude. I don't know but I think I'd take this over the last 20 years of Twins being either middling or terrible...maybe...the Royals have had some really, really awful seasons...
