If Froch is using Tatevosyan's loss to Bute as some kind of measuring stick he is going to have to go some to better him. If he doesnt dominate him on the cards that makes him no better than the three fight novice Tatevosyan lost to previously

Froch would have to up his game plenty ot put a dent in Calzaghe. He'd probably also need Calzaghe to be off the boil as well.
