Matthysse is deadly and one of my favorite fighters.

However, sometimes a good aggressive pressure fighter and smother a knockout artist like what Hatton did against Tzyu.

Then other times the aggressive pressure fighter gets knocked out like Barrios against Freitas.

I think Matthysse's power is absolutely overwhelming for other 140 lbers and he is a rarity for big punchers; he's a clever, patient boxer as well.

I'll pick Matthysse by late stoppage, but he's going to be in for a tough tough fight.
