According to Fox Sports Ken Rosenthal :
Former A's and Brewers manager Ken Macha could emerge as a candidate to join the Mets' coaching staff, perhaps even as bench coach, if the team hires Terry Collins as its next manager. Macha and Collins were teammates in the Pirates minor league system in 1972-73. Macha knows the NL from managing the Brewers the past two seasons. Collins hasn't managed in the majors since '99.
No word yet on the future of former Mets GM Omar Minaya, who was fired with two years left on his contract. Minaya will meet with new GM Sandy Alderson to discuss a potential role, but no decision's expected before the holidays. The Mets would benefit from Minaya returning to his scouting roots and helping the team with his ties in Latin America.
Regarding Beltran's trade possibilities:
Add the Mets' Carlos Beltran to the list of potential OF/DH solutions for AL clubs such as the White Sox and Rangers. To trade Beltran, the Mets would need to assume a significant portion of his $18.5 million salary for 2011. Beltran, 33, has a full no-trade clause, but probably would jump to play in a hitter-friendly park in his walk year.
All three of these rumors I love especially the one about Beltran.
