I'm a very big stats nerd and rarely make any threads but I felt compelled to share my thoughts on our latest acquisition. My analysis is based on his 08-09 stats.
The Basics:
Per 36 stats:
13.1 points, 6.3 rebounds, 2.6 assists, 2.5 steals, 1.6 turnovers
Pace-adjusted stats:
15.5 PER, .544 TS%, 10 Reb%, 10.4 Ast%, 3.5 Stl%, 0.9 Blk%, 11.5 To%, 16.7 Usg%
Overall, Ariza is a good efficiency, average usage guy. He rarely turns the ball over, shoots okay, and doesn't use a whole lot of possessions. He's not much of a rebounder for his size, not much of a play-maker. He did however, shoot exceptionally well in the play-offs (61 TS%) while turning the ball over a bit more, which makes sense because he was playing the best defenses (including our own). So the above stats are what I like to call the "results" stats: they show what his contribution on offense aggregates to. To me, they are not very useful unless you understand how he arrives at those numbers. Let's break down his offense and see how he arrives here.
Offense:
Ariza has a healthy mix of inside outside game. He shoots 56% as outside jumpers (.420 eFG%) and 44% (.625 eFG%) inside. He does not shoot a whole lot of threes and hits about 31% when he does. 78% of his jumpers were assisted which indicates that he's a catch and shooter. However, only 44% of his inside shots are assisted: he drives to the hoop and makes a good amount of them as his percentages show(!). When he drives, his shots are rarely blocked (15%) and he draws a fair amount of fouls (11.7%). Again, he's not a passer, he's either going to shoot or drive (think Wafer with more driving). Overall, he's a very competent offensive player and comparing him to Artest, he provides better efficiency but lower possessions. One would assume his usage rate will go up to the low 20's as he'll have a bigger role on this team. Let's hope that his efficiency holds up.
Defense:
To me, defense is Ariza's absolute calling card. He's simply a defensive stud. To demonstrate, he had only .3 less defensive win shares than Artest while playing 457 minutes less. He creates a ton of turnovers using his long arms (steals 3.5% of possessions, deflections) and he does it by reading the passing lanes not gambling on the ball, as evidenced by his crucial steals against the Nuggets. He has a solid DRtg of 102, the lowest on a very good defensive team, tied with another solid defender, Lamar Odom. The Lakers hold their opponents to .6 less points per 100 possessions when Ariza is on the court. This number is actually pretty impressive considering the guys he's replacing are great defenders (Odom, Bryant). His length gives opposing players a difficult time to drive around and he does a solid job of funneling his man to help defenders.
Conclusion:
Overall, I think Ariza will seamlessly fit into our system with his defense and above average offense. I think he's already as good of a defender as Artest and we can groom him to eventually replace Battier. If he could improve his passing and ball handling, therefore increasing his usage rate in the 20's (there's plenty of reason to believe he'll improve, he just turned 24 and his turnover rate has been going down every year), he could be great on offense as well. I personally don't think the guy is a bargain at the MLE and Morey made the right choice, getting a younger guy whose production pretty much equals Artest's for the same price.
