I believe that Lawson will improve his D like Harden did this past season, being around others that play D will make Lawson a better player on D. He will not be a stopper but will do a better job on playing D. It will fun to watch this season. The West is be a tough all season long.
With Howard and Capela patrolling the middle all game long... we will be just fine on the defensive side of the ball. DMo is our best on the ball defender in the paint according to player shooting percentage and Bev's biggest asset is his irritation factor. Harden actually was a decent defender last season and Ariza is an above average defender.
Sometimes Pablo and Terry both on the court at the same time. Terry was over used. Now he can come in as an assassin for spot minutes to score...back to why the Rox signed him to begin with. So now you've got Lawson that other teams NOW need to worry about playing defense against versus dropping off to double/triple team Harden.
