KO - You didn't read my post, I said better Power not better boxers.
VM - Over the three you mentioned - I would tip Griffith to beat DLH on points, but I think DLH would have been too quick for Napoles although as we both have said DLH was at his best at Light Welter/Light. So perhaps a little hard to compare.
Think he would have been too fast for Tszyu, although the last 3 rounds might have been interesting.
