I don't think that 165 was an upset at all. Lewis's two losses are to Marinelli. Both Lewis and Campbell have wins over Valencia. All of these guys are AA contenders, but are hardly separated by rankings. Plus, Lewis's international experience is remarkable.
I'm a Buckeye fan, but I was thoroughly amused by DeLuca. The tongue thing was a little weird, given that the match was still on, but he went for broke twice and won it in very exciting fashion. If a top ranked guy did that while whooping on a lower guy, I'd understand the criticism. But when a guy comes from behind like that after taking a couple of risks, I'm inclined to celebrate for him and certainly don't hold his expression of excitement against him.
