YES! he can be legit from here on out and he will not go down as a cheater.
OFFER HIM MONEY TO PROVIDE EVIDENCE OF THE PRE-THREAD RUNS. The desert story is fishy. Kansas is fishy. The beginning was fishy. His triathlon claims are fishy. Come on man, flex your muscles! Go for the kill. Don't be a pu$$y, be Darth Vader! AND OFFER CASH DIRECTLY FOR THE CHILDREN! He cannot refuse. DON'T WAIT LIKE YOU DID WITH ROSSI
Those splits prior to the OP are what we need to put the nail in the coffin.
