Don't think it's needed. Remember, Martinez took the first fight at short notice and had to jump up a weight division (Williams had been preparing for Pavlik at 160lbs). He still won the first fight in my opinion despite that, and then the second fight......
I thought Martinez was taking it, but it wasn't as wide apart as some people are claiming. Martinez was landing with more pop and authority, but Williams was still landing fairly frequently. Addie apparently thinks he was watching Pac-Hatton (although, in fairness, the KO could have come straight from that fight). I say let Williams rebuild and, if he gets back to the top table, let them go again. LancsTerrible made a good point about Martinez age, though, I keep forgetting he's in his mid-thirties.
Its very hard to remember he is as old as he is when he does what he has done recently. The guy is looking great (no homo).
