We've discussed in previous seasons some of the advanced stats available. The one I have found most often reflects what the eye test says for me is BPM at BasketballReference.com. It calculates the points per 100 possessions a player contributes above a league average player. It is similar to WAR (wins above replacement) in baseball meant to boil the all around game into 1 number. It has an offensive component and defensive component. Here is how the Bobcats shake out:

A Clayton +5.0 (O +4.7, D +0.3)
A Sheldon +2.7 (O +2.2, D +0.5)
J Hunter +2.1 (O +2.0, D +0.1)
S Mitchell +1.6 (O +1.5, D +0.1)
A Hadaway +0.4 (O +0.4, D 0.0)
M Brown -2.1 (O -2.6, D +0.5)
E James -2.4 (O 0.2, D -2.2)
G Wiznitz -3.5 (O -3.8, D +0.3)
A Brown -4.3 (O -2.8, D -1.5)
I Cornish -5.9 (O -3.7, D -2.2)

Immediately some validating things jump out at you, like Miles really struggling to contribute offensively but still a very good defender. Similar with Wiz. Sheldon with the solid defensive number probably surprises many, but I personally haven't seen the huge defensive liability others have. And it confirms the disappointment many have had in Ike.

I've been really high on AJ all year and I really think his usage rate needs to go UP. Someone needs to tell him he really is one of the best players in the MAC. I just feel like a little more swagger and killer instinct and he could take off.

They also have "Win Shares" and have it by 40 minutes, the thought being an average .500 team has 5 players with WS/40 around .100 and if you have 5 guys up around .200, you're very tough to beat. AJ Clayton also wins that one far and away with .205. The others are similar to the BPM except a little kinder to EJ & Wiz.

From that site. This says NBA but I would assume the scale is the same. Accordingly we have 3 good or better starters and 5 end-of-bench players.

To give a sense of the scale:

+10.0 is an all-time season (think peak Jordan or LeBron)
+8.0 is an MVP season (think peak Dirk or peak Shaq)
+6.0 is an all-NBA season
+4.0 is in all-star consideration
+2.0 is a good starter
+0.0 is a decent starter or solid 6th man
-2.0 is a bench player (this is also defined as "replacement level")
Below -2.0 are many end-of-bench players

I really like your third question Joe. Now that I have grandkids playing at the junior high and varsity level, I'm always intrigued by substitution patterns that put all or most of the bench players in together as opposed to putting one or two kids on the floor with the starters. Sometimes the "all in together" practice results in a circus atmosphere and little real experience in my opinion perhaps skewing a player's real value relative to the statistical model cited.
