23 games into the season, the Bulls stood at 8-15, and had a per game point differential of -13.5 from games 11 to 23.  Then we beat the Knicks, and we've gone 14-7 since.

Here are the Per36 numbers of our key cogs before and after that game (one note: I used game logs from cbs sports, and I just noticed they haven't added last night's game yet, so these numbers don't include that game.  Shouldn't change the stats much though).  The first line is before, the second line is after:

One other thing I haven't seen mentioned: Rose's Per36 assists by location, before and after the Knicks game.
