His coverage was decent at best. He gets a lot more credit for being a good tackler and the fact that he's not afraid to lay the hat when he needs too. I think people put too much emphasis on this and it's misleading. People think because he is making tackles that he is making plays. While this is somewhat true it is really not realavent to being a top 5 corner. Corner get paid to cover not tackle. Dieon Sanders is possibly to best corner to play the game, but he couldn't tackle for crap. Dunta is maybe a top 15 corner when healthy IMO. In addition to these I would add: Al Harris, Chris Gamble, Champ Bailey, Darelle Revis, Carlos Rogers, Nate Clements, Antonio Cromartie
So his agent stalled the Texans because they thought they could get on the free market without a franchise tag. The Texans were like WTF they are stalling we are not gonna let him go for nothing franchise him. Then his agent is like oh crap we still have the nego with them, my ploy didn't work.
