While Aroldis Chapman, whom the New York Yankees acquired in a five-player deal Monday, is one of the best one-inning relievers we've ever seen, he faces both a legal investigation into a domestic violence allegation and an MLB investigation that could result in a lengthy suspension. The Reds' return in Monday's trade reflects the possibility that he'll be charged and/or suspended.

There's no question that Chapman is the most valuable reliever in the game today.
