O.J. Mayo tried his best to guard Chris Paul for much of Wednesday night's loss to the Clippers. Mayo got the same lesson that everybody else in the NBA gets – it's not a one-man job. But while Paul carved up the Mavericks for 19 points and 16 assists, it was the inability of the Mavericks to respond to tougher situations late in the game that had Mayo concerned after the fourth loss in a row. "We got to want the game," Mayo said. "We're struggling right now and teams are not just going to fold and give us the game. They feel like if they keep going hard, they can get it. We got to have the mentality that when they gas it up a little bit, we have to have that same energy." There seems to be a stretch of four or five minutes late in every game that the Mavericks fail to bring the same resolve that the opponent has. That's been their fatal flaw and something that has to be fixed, starting Thursday night against the Kings.
