This guy changes trainer names more times than most ploppers change their underwear.  Wasn't it a woman?  Sheila something?  Then it's Steven Finkelstein...now it's a different Steven Finkelstein.  And who is this knucklehead Matt Medeiros who is down on a couple for him including one of the best half mile horses in the game.  What's the deal and who is pulling the strings behind the scenes?  Anyone have any insight?
