A classic "unstoppable force" in Diaz versus the "immovable object" in Katsidis.
It does take a little (but not much, Margarito did lose to Williams then came back to tko an unbeaten Cotto) off this fight with each one coming off a loss, but their styles alone should make this an extremely exciting fight.
I will almost go as far as to say that out of the top 8 or 10 lightweights out there right now, these two would be the most entertaining match-up because we are going to see an all out brawl.
Katsidis is going to have to win by kayo or points on knockdown, otherwise I see Diaz winning this with superior boxing. Don't know if he has the power to kayo Katsidis though...
I probably gonna watch this live, and hit up one of my friends for a tape of the MMA, that's how strongly I feel about this, although I would like to see Chuck live as well.
