Let's not get too excited he was signed for league min w/partial guarantee. That video is from 3 seasons ago and he hasn't done much worth talking about the last 2 years. He'll get a chance in camp and preseason to prove himself, but he could be out of the NBA if he doesn't stick with us.
No doubt Williams is a slick 3 pt shooter but he does not deserve the same esteem as Delfino, at least not yet. Delfino could play multiple positions (2,3 and even 4) and play some D. Role player he surely was but Delfino's contribution is still underrated by fans.
THIS...Delfino was huge for us last season! Don't think he ever got enough credit. Just hope Garcia can pick up the slack.
