From Devin Kharpertian of Netsarescorching:
T-Will at his best is a great passer, slasher, and facilitator. At his worst, he forces offense, commits far too many turnovers because of poor decision-making, relies on fading jumpers or 3′s he can’t make, and tries to make the best looking play instead of the best play. Extremely athletic, grabs a surprising number of rebounds for a guy with his size. Can defend three positions, is built for a sparkplug sixth man role as long as he has shooters/scorers around him.
Also he can dunk the hell out of the ball.
Sebastian Pruiti on Terrence Williams:
He is fantastic when he is determined to get to the rim and when he is looking to get his teammates involved. When he is settling for jumpers or in shoot first mode he can be very bad. Tends to turn it over trying to make the spectacular play. Not really involved on the defensive end. A good 6th man in my opinion.
