At least Sasha went down shooting. <img>
On a side note, the reason Dwayne Jones went in the game is because they called a shooting foul on Evans for undercutting Sasha, but when he couldn't take the shots, Cheeks got to choose whoever he wanted to come and take the shots. With the Wisdom of Solomon and access to advanced NBA stats ... he selected none other than Dwayne (Hey Dude. I'm hitting 52% of My Free-Throws, Why didn't you pick Ben?) Jones who obliged by missing a pair.
As for LeBron, I just think the team is more focused on what they need to do when he's off the floor. They're aggressive because they realize they have to get it done and can't just flip the ball back to LeBron. They know they need to play inside out through Z or at least drive and cut to try to create something. I think the defense also relaxes in to 1v1 coverage which allows the plays to actually develop the way they're supposed to.
Keep in mind, LeBron's mere existence makes everything tougher for this team. Road stadiums are packed. Games are on national TV. The opponents for the most part get up for the game and the chance to beat LeBron. But just like the Cavs have lapses where they stop focusing and let the other team back in, so do our opponents. Of course they're going to happen when LeBron leaves the floor.
