Entering the 2012-13 NBA regular season, one of the Chicago Bulls' greatest strengths was their second unit.
With sharpshooters, defensive specialist and aggressive rebounders running about, Chi-Town could make a case for having the top bench in the league.
After ranking seventh in Defensive Rating in 2011-12, they now rank 19th in 2012-13. Chicago also ranks 27th in second unit points and 27th in second unit rebounds per game.
They ranked 10th in rebounding in 2011-12.
The cure to said woes may just be second-year player Jimmy Butler. The guard-forward hybrid brings infectious energy to an otherwise sluggish second unit and provides a boost in every statistical category.
In just 14 minutes, Butler finished with six points, two rebounds and one steal. Although the numbers may not blow you away, they are evidence for his aggression and effort on both ends.
If the numbers don't do it for you, try turning on a Bulls game. Butler is one of the hardest-working players in the league.
