Last week, Stephen A. Smith appeared on Sirius XM's Karen Hunter Show and explained why he and Glenn Robinson despise each other.

"I saw this man march lock step with what (former Bucks Coach) George Karl wanted to do ... but Randy Ayers becomes the head coach of the Philadelphia 76ers ... you treated this man like trash, but you'll come and talk to reporters about how brothers need to facilitate brothers being hired, but you had one and how'd you treat him?"

Earlier today, Robinson spoke with TMZ Sports, revealing where their beef started and proposing a sanctioned fight with Smith in the future.
