While Williams might make a modest impact, there is no guarantee that he will get minutes in the first place.
However, while Rick Adelman would have kept him stuck on the bench, with Musselman and his "strange" substitutions...anything is certainly possible. I'm all for the boat of trying to showcase new players, given that players such as Cisco and Salmons have had hot streaks coupled with cold streaks (in other words, inconsistencies), and Williams' tenacity for rebounding and shotblocking

may be something we have not seen for a while. I still think his game lacks polish and that he generally lacks NBA experience, but hey...give him 6-10 minutes, see what he can do. If he pans out, stick with it. If not, uhmm...continue moving forward...or erm, downward.
