Primetime = Serious bias commentry in favour of Marquez

I think bad commentators make their minds up too early in a fight. After a couple of rounds of praising one guy, they don't seem too eager to change their minds regardless of what is happening in the rest of the fight. Even if Ricardo and Khan would usually be biased towards Pacquiao, after a few rounds of Marquez outboxing him, it's certainly possible that they'd carry on giving Marquez the edge. It's hardly uncommon in sport and it's not about bias, it's just bad commentary.
