I'm  not complaining here, I just enjoy trying to figure out this kind of thing.  Maybe it's just random variance, but I doubt it.

whatifsports.com/hd/PlayerProfile/Ratings.aspx

a few notes:
-Dearborn played SF probably 60% of the time this year, while he played SG probably 95%+ last year.  
-Teammate Penrod emerged as the teams best scorer this year, after being a non-factor last year.
-In general, big men this year were better scorers than last year (though not necessarily better players).
-Last year's 3 was an excellent slasher/rebounder, probably the best player on the team.
-Dearborn had lower distros this year than last, especially after it became obvious that his efficiency wasn't very good anymore.
-I run the triangle

I realize that Dearborn is a poor rebounder at the 3, but would you expect his offense to be affected this much also?
Or might it have to do with distro/offense/team composition?  Maybe the presence of the slasher 3 last year got him some more open looks?

i have no idea why there is a large space in the middle of the word random.  i didn't do that

It's that wacky Senior SG Curse again.  Weird.

It's also partly the shift to sf, with not that high of lp.
