This fight is a rematch of the IFL (International Fight League) bout between Ben Rothwell and Roy Nelson, and the UFC should book it for a number of reasons. First, it would be interesting to see the development of each fighter. Nelson went from the IFL to Ultimate Fighter champion. Rothwell came into the UFC but was never really a top heavyweight, just sort of hanging around the top 15, but a recent knockout of Alistair Overeem has popped him into the top 10. Rothwell got the better of Nelson back in the day, but would the fight go the same route? Probably not, but it would be fun to watch, as both men can give and take a punch.
