It addressed my point: when you have a weak rebounder and defender in Bargnani, you need a strong rebounder and defender in Johnson - and Johnson's weaknesses on offense are offset by Bargnani strong offensive game.When the core (Bargnani, Bosh and Hedo) is in, the Raptors play much better with Calderon at the point (9 points better than average) than with Jack (4 points worse than average).
When Chris Bosh is out and Amir Johnson is out the Raptors get killed (16 points worse than average). But when Amir replaces Bosh the Raptors are only 1 point worse than average. Breaking it down further we find that with Johnson, Bargnani and Jack in and the other two players chosen from Wright, DeRozan, Calderon , Bellinelli and Weems the Raptors are 19 points better than average in 143 minutes!
Bargnani, Bosh and Belinelli in is great (218 minutes, Raptors play 15 points better than average). With Wright also in the Raptors are awesome (60 min, 33 points better than average per 48 minutes!).
Adjusted +/- is not the "be all end all", but there are a few key combinations that make sense. Especially given how weak our defense is with certain combinations.
A "new" system, dubbed "Regularized Adjusted +/-" shows some telling stats:
On D, Andrea Bargnani is ranked 529 out of 537 players. Yes, you read that correctly.
Bargs' lovers - I'm just relaying information.
Amir Johnson is ranked 11 out of 537. Yes, you read that correctly.
Amir haters - I'm just relaying information.
Argue with the author of the data, not me.
