It took only two exhibition games for Kings coach Paul Westphal to see the effect Jimmer Fredette could have on the team's offense.Though Fredette can have an impact without the ball, Westphal said, the Kings need to get the ball to the rookie more often.With Fredette's shooting and playmaking ability, teams will have to monitor him at all times, which should open the floor for his teammates. With the season opener against the Los Angeles Lakers four days away, the Kings are still learning how to do that."I think our spacing needs a lot of work," Westphal said after Wednesday's practice. "I think we missed (Fredette) a few times where we should have got him the ball."
