Postol Took Matthysse's Soul

I am really impressed. He is not as chinny and featherfisted like many of us have thought and now I understand where his power comes from: He throws single punches in early rounds, but when Viktor figures you out, he starts to put some weight behind punches and throws sharp, precise combinations. Thats the type of counterpuncher I really like. Postol probably the first guy who beat Matthysse fair and square (even without KO I gave Lucas only three rounds - 1,2 and 6) and I was shocked seeing Matthysse quit, but no wonder there, Viktor like a surgeon, sistematically dismantled him and broke him mentally by outboxing him and physically by landing hard combos in later rounds. What do you think about Matthysse's mental state? The post fight interview with him was very strange...
