The length of these tournaments would be collosal, id be all for it if they somehow got the fighters in the ring every 3 months as opposed to the 6 - 9 months we saw in the super 6. Id be interested to see if the powers that be could pull it off but id be sceptical. The sheer amount of ego's this sport has will make sure we never get to find out.
Not many people think Dirrell was lying, and I think it's unreasonable to say that he was mainly because of the lay off, a guy whos stock has never been higher wouldn't lay off for 18 months.
