I don't blame Dwight for giving up on D. Not saying he did, but you're suggesting it so... heck, when I play ball and I don't get the ball, I start slacking on D myself. LOL. It's a natural human mentality.
At least by Howard calling for the ball more, he's willing to shoulder the responsibility for the loss. Unlike SVG who will place the blame on his players not scoring. Way to man up Dwight. I see a vocal leader emerging and it's nice to see.
