Except that BJ outstruck GSP for the entire fight...
Well no, it was the other way around. Unless you only count head shots as damaging blows. GSP out-struck BJ in all 3 rounds. As far as percentage of shots landed BJ edged out GSP so you could very well argue he was the more technically sound striker that night.
The second fight was a blowout, with GSP landing a very high percentage of strikes thrown. I would say GSP was more technical that fight.
As for JimmyJames. How can you not rank Anderson as a technical striker?
