The topic is 'who should be ranked number one'.
Not who is going to win the super 6.
or even 'who is best?'.

Abraham can't be number one ranked supermiddle after one fight in which he beat Jermain Taylor.

Only plausible answers as to who should be RANKED 1 are Ward or Froch.

Remember its a different question to 'who will win super6?' or 'who is the BEST supermiddle?'.
