No.
There is no way he's competing with our main guards (Smart, Thomas, Bradley) in terms of the ability to earn minutes right now, and when the rare opportunities do come up for another guard to play, I'd rather see Rozier and Hunter get those minutes - I believe they both have far higher upside than Pressey.
Love Pressey as a player, love his heart and love his 'Pure PG' passing and dribbling skills. But at the end of the day those things only get you so far, and Pressey has two glaring weaknesses (lack of size on defense, complete inability to score) that make it hard to leave him on the court for long stretches...and hasn't shown he can overcome either of those.
He's had his chance and he's performed admirably, but I think it's time to give somebody else a chance.
