Not really sure what this accomplishes for either guy. In an ideal scenario they would match two top guys who were still on top level in respected sports. Of course Lacy would give all to have been effective there at all. Both could pulverize the other into powder then go into foes arena and experience the same fate. Lacys toast and his power has always been overstated, turned him into a unrealized injury pron one trick pony. Not familiar with Diaz really, heard he's quite the asshole and has a brother. Bout it.
