It would be great if he can play 20 minutes.
Keep in mind, not having Sprads changes the ability for Tay to come in for Angel. I firmly believe one of the main reasons that Tay hasn't started is because he is by far our 2nd best option at PG. Its not as big a deal now because Angel is avoiding the silly fouls, but early in the year it was nice to have Tay as our first option for Angel or Sprads, and most often it was for Angel.
But as the year has gone on Angel has stabilized and played more, and as that happened Tay has played more at the 2 and Will has played less. Of course the last couple were because of Will's injury, but often it was also because Will couldn't guard people. To Will's credit, he finally found his shot and IMHO is giving us exactly what we need. Plus, Tay has gotten more of his minutes.
But its foolish to hate Will so much to not see his value, and that him playing 20 minutes a game is better for this team and not worse. So yes, we need to hope he is healthy and can give us another solid option on the perimeter with Angel and Tay.
