I saw a stat that the jazz are 17th in the league offensively. Seems near the middle of the league to me
Some offensive stats:
27th in ppg @ 93.3
20th in FG% @ 42.4
3rd in 3 pt % @ 37.4
5th in TOs per game @ 12.7 (big improvement over last season)
24th in FT% @ 72.0
9th in Offensive rebounds per game @ 11.5
30th in Assist per game @ 16.5
19th if offensive effeciency @ .982
28th in fastbreak points per game @ 8.2
20th in points in the paint per game @ 41.7
per ESPN & Teamrankings.com
Not dead last over all but certainly I'd say bottom 1/2 to 1/3 of the league overall. Clear room for improvement.
