Anyway, the point of my post was that if you want to go from really really bad to really really good in only 4 short seasons, this is what I personally suggest:
1) Year 1, your first round pick has to be stud, MVP/Cy Young caliber type player. Second round pick has got to be starting caliber. Sign 2 IFAs that are All-Star caliber.
2) Sign at least 2 very good, high quality, hopefully even All-Star caliber free agents in each offseason.
3) In Year 4, you will be able to make a very good run. You've got your ML ready first and second round picks and 2 IFAs (4 players total) from Year 1, and You've got 4 seasons of signing 2 good FAs (4x2=8 good FAs). That's 12 very good, All-Star caliber players plus maybe hopefully 2-3 that were by the previous owner which 14-15 for a very good solid core.
If you don't sign those ML FAs though, it's going to take longer than 4 years, period.
