2007-08 TEAM OFFENSE

2008-09 TEAM OFFENSE

Last year the Hawks were good at getting to the free throw line and rebounding their (frequent) own missed shots. This year, the aren't getting to the line/making free throws* nearly as often or grabbing offensive rebounds as often (though they're still in the top third of the league in that regard) but their much improved offensively because they're attempting more three-point shots and making a higher percentage of their shots from beyond the arc.

*07-08 FT%: 77.2

08-09 FT%: 73.3

FIELD GOAL SHOOTING

The Hawks are actually shooting much worse on two-point attempts (This may be a concern as their three-point percentage inevitably declines.) this season but that's more than made for by attempting more than 21 three-point shots a game and making almost 43% of those threes.

2007-08 TEAM DEFENSE

2008-09 TEAM DEFENSE

The opponents' eFG% and FT Rate should go down some once Josh Smith returns and their TO% should go up. Josh Smith makes it difficult to make shots, he creates turnovers, and he doesn't foul as often a the guys who have taken his minutes, be it Zaza Pachulia, Solomon Jones, Randolph Morris, or whoever's taking a turn as an undersized power forward. He probably won't make much of a difference on the defensive glass. The Hawks just aren't a very good defensive rebounding team.
