I like David a lot, but he even lost this past fight. He is 1-4 in his last 5 fights. I know all those losses are by decisions, but that doesn't cut it to get back in the UFC. He will have to win at least 3 fights in a convincing fashion for him to even be considered for a return to the UFC.
I know the MW division is a joke right now in the UFC, but if David cannot win against guys that are about the same level as him, the UFC will not be knocking on his door to get him back.... then again, they did call Ivan Salaverry bakc after two losses.
