Grizzlies' Stephens gets way up to hammer home alley-oop

D.J. Stephens is looking to crack an opening-night roster after falling short the past two years, and he made quite an impression in his preseason debut with the Memphis Grizzlies on Monday night.

The undrafted shooting guard - who played four years in Memphis as a collegian - put it all on the line to slam home this lob from Andrew Harrison, leaping and dunking with such force that he went down hard on his tailbone.
