Defense still focus for Phoenix Suns' 2nd unit

What separated the Suns from the playoff pack last season was the bench.

Five reserves comprised a unit with a distinct style and personality, giving the Suns a 10-man mix and a wave of unselfish, energetic game-changers who eased the load on veteran starters.

 
The Suns again turn to a five-man bench to carry the middle of each half and ride hot hands to the finish. As it was prior to last season, success off the bench this season is no sure thing - mainly due to a lack of familiarity.

When Goran Dragic runs the second unit, Hakim Warrick and Josh Childress give him a new look to handle. Now, Childress is indefinitely out with a broken right index finger, and Channing Frye feels behind with "heavy" legs and shots falling short.

"It's still more of an athletic team with Josh," reserve Jared Dudley said. "Defensively, we have the potential to be there but Channing and Warrick have to help us out, just because bigs are crucial in the NBA. It takes time and that's why chemistry is going to be huge.
