The defense was lacking early & then picked up, which happens quite a bit before adjustments. But Bynum & Royal hurt them bad. Combined 10-14 from the floor, & 4-6 from three (they both shoot under 30% from deep for the season). It's those two, plus the TO bug returned.
It looked like Blackwell was shrugging off a mediocre start, but then committed his 2nd foul on a call off the ball, effectively making OSU's job much easier for the last 6 minutes of the half. Boyd is being defended well, but either way Blackwell just can't afford to be taking himself out of the game like he has been recently. Be smarter.
Missing from three (1-8), but not enough attempts to really point to that as the main culprit. Just get more stops, try to get out & run, and it would be nice if Bynum & Royal came back to earth.
