This all seems a bit smoky at present - it seems none of the parties are clearly announcing their intentions.
I think it breaks down like this:
1) MLB would clearly like this to "quietly go away." As a secondary position they will gun for A-Rod since drawing new fans or keeping old ones (based on the integrity of the game), outweighs A-Rod's draw/costs of a hush-up.
2) The Yankees want salary relief. If they could walk away right now with no liability, they would. A-Rod has minimal marketing value.
3) A-Rod seems to be at a natural ending point. All the signs seem to point toward an early retirement, in exchange for a huge buyout from the Yanks.
Trouble is, A-Rod is the one making the choice here. I see him going forward, regardless, a la Armstrong, and trying to hold onto his endorsements and/or remaining salary. I also expect MLB to sit on their hands as long as they can about this. I'm surprised we haven't heard more about it.
For what it's worth, the New Times is a weekly, but they have done some very good investigative journalism in Miami in the past. The Miami Herald covers a lot of big "already known and talked about" stories, but if anyone "broke" a new story that was under the radar, I'd assume it would be the New Times. They're legit.
(Disclosure - I know several New Times reporters on an 'occasional drinking buddy' basis, but some of my good friends are good friends with the staff and reporters there.)
I'm not following this story closely, but if anyone has any Miami-specific questions, PM me, let me know, and if I have any decent info, I'll post it here.
Final thought - the Armstrong situation has probably grossly impacted all of these types of cases.
