Showtime won't put Dirrell in front of Bute in March, even if he's ready and wants it. They will keep that fight for just before the big fight between the winner of Kessler-Dirrell-Bute and the supers 6 winner.
The smart move would be to at least put Bute & Dirrell on the same card in March in order to hype their fight a few months later. Bute confirmed he'll fight 3 times in 2011 and Dirrell or Kessler are sure to be one of them bouts.
Alright, let's hear who you think he should be fighting. Feel free to back it up with plausible circumstances (division, PPV network, March '11, decent ranking). Most names you'll list would just say no to Bute @ 168.
