Again, I think it depends on the situation. For the Twins, I think it was probably going to take 5 years minimum because the farm system essentially had to be rebuilt and that is about as fast is reasonable to expect prospects to be drafted and work their way through the pipeline. I'm not absolving the Twins of anything here BTW. Had they not drafted relatively poorly for a period and not made several bone head trades during the same period, the road to success would have been considerably shorter (especially the bone head trades). You can't turn Johan Santana, Bartlett, Garza, Wilson Ramos, etc. into nothing and not have it set you back a bunch. Not to mention to double down on the blunder by getting nothing for GoGo and then JJ Hardy. Add it all up, you have a lengthy process even done if optimally.
