Memphis Grizzlies center Marc Gasol should win the Defensive Player of the Year. All you need to do to understand why is to watch everything he does away from the ball during a game
To understand why Memphis Grizzlies center Marc Gasol is the league's best defensive player, you need to watch him very closely. Spend a game ignoring the ball and just focus on what he does on the defensive end of the court. Do that enough times, and you too will see why he's a basketball savant.
I spent my time watching Gasol during the Grizzlies' 96-85 win over the Los Angeles Clippers Wednesday, a pivotal win that gave Memphis a leg up in the race for the all-important No. 3 seed in the West. It was one of those odd Gasol games where the stat sheet actually told a large part of the story. Gasol scored 21 points to lead Memphis' offense and was credited with five steals, a rarity for him. But there were so many defensive possessions where Gasol's positioning, anticipation and on-court intelligence forced misses without him getting any credit in the stat sheet. These are just a few of those possessions.
First, it should be noted that Gasol has excellent natural quickness. Look at him stay with Chris Paul on this switch.
But in today's game, lots of centers can stay with quick point guards for one possession when needed. What sets Gasol apart? He combines that natural ability with superior positioning and fantastic play recognition.
