Maybe league rules, but I think the Cincy player meant to arm bar the Purdue players chest but missed high. Tough break, flagrant 2 was the right call.
Booker should start, get all minutes from first platoon and half minutes from second platoon in first half. After under 8:00 minute timeout in second half, I'd like to see him in 6 of those 8 minutes.
The out of bounds calls made twice by same ref should be reviewed by league...this guy should lose a few assignments over this. This team doesn't need any help looking bad.
