I know that in my article, "Four True Outcomes", I speculated that Mike Scioscia might have been part of those trade discussions, so Gammons article lends a small amount of credence to probably three different scenarios: 1) Arte didn't want to do business with his cross-town rivals (which I had been potentially worried about when I suggested it in my other article, "Trade Candidate: Howie Kendrick?", 2) Moreno is too involved in the actual trade negotiations for his own good, or 3) that S-C-I-O-S-C-I-A was a part of that trade package and Arte couldn't bring himself to let him go.
Of course the former two are the more probable scenarios. Moreno was quoted recently as saying, "I have to look in the mirror and say, 'Am I making the right call?'"
He may have been referring to those very trade negotiations.
