PFT Rumor-Raiders MAY lift tag from Asomugha

Ok, I know none of us really watch Raiders games, and I know that he is a good man corner, but where did he get his billing as the best man corner, better than Champ as one poster stated? This is an honest question, because I know he had a great 2006 year, but has anyone looked at his other years? I doubt it's because they don't target him (for 2004 and 2005 anyway, maybe they didn't in 2007). I do think he'd fit our system perfectly, but I'd love to know besides 2006 how he got his billing.
