I am absolutely certain that he didn't give up ANY 3 point shots to Bell because he "lost his man" in the sense of not paying attention or not giving effort to keep up with him. I don't even need to check Tivo for that.
But you're glossing over the point I was making, namely that defense is a TEAM responsibility and that if Vince "lost" Bell, it was because he was deliberately helping someone else who either lost their man or was at a serious disadvantage in a matchup or floor situation. It then becomes the responsibility of someone else on the team to identify Bell as open and get to him in time to bother his shot. No single defender can be two places at once, and it's not fair to expect a player who rotated to the lane stop a pick and roll or collapsed in transition to stop a layup/dunk to also be able to recover out to the 3 point line when the ball is immediately swung.
Slamming VC's defense is the easy, knee-jerk, mindless thing to do. It's been done so long by others that it must reflect truth, right? It's certainly much easier than critically watching games and seeing that Vince has actually been this team's best defender since February and that, despite many poor defensive performances in his NJ tenure, he has also had any number of excellent defensive performances. It's legitimate to look at his career and observe that he has played lazy defense on a lot of possessions in the past and has frequently not been physical in negotiating screens. But it's also legitimate to observe that he has been focused, attentive, physical, intelligent, and consistently diligent on the defensive end since he took on the leadership role of the team post Kidd trade. He's not flawless defensively but I find little fault with his effort or individual defense.
hahahah.
