He should ask for more playing time, he deserves it - we just have an incredibly deep guard rotation of Brown/Smart/Brogdon/White.
Pritchard's sweetspot is 20-29MPG off the bench, where he has averaged 10.5/2.5/2.5 in 4 games this season (doesn't include games of 30+ mins, because I do not think that is his role). His career splits in that 20-29MPG role are 11.4/3.5/2.9 on 50/47/90 shooting, playing 37 games and averaging 24.3MPG in that spell. That is basically prime Patty Mills (slightly better, actually).
He'll never get the minutes he needs to get here, barring something major and unforeseen, like a mega trade involving two of our four main guards or some seriously bad injury luck. Let's win a chip with him this season, and then ship him if he still wants out.
