Nate played Sergio a nice amount of time yesterday because he did not make mistakes, hit his shots and tried to stay in front of his man on D - so the above statement is bullcrap.
I said it before and I will say it again - the reason Sergio's minutes are limited is because of his play. If he plays like a real NBA PG - he will get minutes.
Nate has nothing to lose by putting a good PG on the court - and when Sergio plays like one (as he did last night) - he gets the minutes.
Time to get your collective heads out of your man-crush covered towel and see what is really happening...
The same was true of the unfounded belief that Nate will not play Rudy - Rudy plays like an NBA player - and he gets the minutes.
There is no mystery to the situation, there is no conspiracy - if Sergio plays properly - he will see minutes - if he sucks - he will not.
