I grabbed the Bruin's record for 2000-2009 and plotted them here:

via i55.tinypic.com

(Apologies for the poor writing.  I'm doing this while waiting for batch jobs)

For the top plot, the blue & red squares are the scores of UCLA & opponents (respectively).

The vertical cyan bars with a dark band in the middle show the mean and standard deviation of the UCLA scores, and the orange/red bars show this for the opponents. (note that 2 scores were cut off USC's 66 & UCLA's 63).  The width of the blue bar gives us an idea of our offensive consistency and the orange bar tells us about defense.  It is notable that the avg opponent score is  higher in both 2003 & 2008 (first year for KD & RN).

For the bottom plot, the squares are the point differentials and the green bars w/ black bands show the mean & standard deviation.  I do not see any obvious correlation between avg(Point Differential) and W-L.  Our 2004, 2005 & 2006 seasons were similar but our W-L records varied tremendously.  The dashed black lines are the median of the point differential and these track a little better with the W-L.

I am interested in comments.

I'm sure I don't have to tell everyone this, but our W-L records for these seasons were:

2000   6-6

2001  7-4

2002  8-4

2003  6-7

2004   6-6

2005   10-2

2006  7-6

2007  6-7

2008   4-8

2009  7-6
