On the heap already:
Jesse Marsch (not to be too much of a rhymer, but that one was harsh although it was supposed to be mutual.
Robin Fraser (when Chris Wondolowski scores more goals on his own than your entire team--well see ya' is all you can expect)
Hans Backe---NYRB still without a trophy.
Who is next?
My money is on Oscar Pareja.
Some others who might want to be checking their cell phone before answering would include Paul Mariner--if for no other reason than it is Toronto. Jay Heaps could be worried, but I think that New England will give him one more year.
