Wanker Spence.... lol. Even Joshua after water cut would have more chances against Tszyu than Spence in 154.
If he couldn't beat Lubin convincingly enough to get a decision then he has precisely zero chance of beating Tszyu. I'll bet you and your lover @ellerbe also tipped Harrison, Ocampo and Mendoza to beat Tszyu. Ramos and Tszyu could fight ten times and Tszyu beats him comfortably ten times.
