Those stats were for the whole tournament though, not just against Kanter. He has a lot of upside, but...

Valanciunas also gets some opportunities from time to time in post-up situations, an area that he's not nearly as proficient. He lacks the girth to establish deep position inside the paint at the Euroleague level, even if that doesn't stop him from trying.
Against weaker opponents, he can put the ball down once or twice and dig a bit for better position to get his jump hook off (showing nice touch and great extension around the rim), but he doesn't really have the strength to finish through contact against high-level opponents.
He needs to work on his left hand and get quicker and more proficient with his foot-work and counter moves, as he doesn't look terribly natural creating his own shot down low.
Valanciunas is largely untested outside of 15 feet at the moment. He's taken one jumper this season—a surprisingly confident looking 3-pointer with the shot clock running out against Zalgiris. It went in.
The rest of Valanciunas' game needs refinement, particularly his ball-handling and passing abilities. He turns the ball over at a pretty high rate and definitely has a ways to go in terms of improving his basketball IQ and overall experience level.
The place this seems to show up most is on the defensive end. Valanciunas is a major presence in the paint with his terrific size and length. His mobility helps him out quite a bit as well. He can contest shots around the rim and has good timing for blocking shots, even if he's not what you would call a high-flyer.
With that said, he's not the smartest, most reactive player you'll find right now, especially on the perimeter, which can lead to some poor rotations and open shots for opponents.
Inside the paint, Valanciunas is a frequent target for opposing teams to post up due to his narrow frame and lack of experience, especially in the Euroleague, where almost every team has a bulky old school back-to-the-basket pivot who can simply overpower Valanciunas in one-on-one situations.
That could be a problem against the much larger matchups he'll have in the League.
He would also get much better weight training over here, though, so it goes both ways. I'm just a little unsure.
