As a heads up, the 2012 entry draft would start roughly 1 month prior to last season if we follow the current FGM rules (see below), because the MLB deadline to sign this year's draft picks is July 13th at 5:00 pm EDT. In prior years, I believe that the deadline was August 15th.
Per the rules:
The annual entry draft starts at noon EST on the day after MLB's signing deadline for draftees.
