Why are manhole covers round? And why are you putting so much trust in your inner circle? Those are the kind of questions you get asked once you've answered most of the pertinent ones, as Trey Burke did last season in leading Michigan to the national championship game. The consensus national player of the year announced he was turning pro last month, and last week the point guard announced he was bypassing more high-profile sports agents to sign with his father, Benji Burke, a newly licensed agent, and his cousin, Alonzo Shavers, who has a relatively small list of NFL clients. And while that move might have raised a few eyebrows, in Burke's eyes it's "tough to really explain" why it was actually a pretty easy decision for him. Negotiating rookie contracts in today's NBA isn't exactly rocket science, Shavers knows how the business works — even though Burke will be his first hoops client — and Burke's family isn't closing the door on the possibility of partnering with a more established agency later on. "I just felt like if we were to keep it in the family I wouldn't be missing out on a lot of opportunities that I would've had if I was to go with a big-time agency," Burke said Thursday at the NBA draft combine in Chicago. "There's always going to be risks either way you go. But I just felt like that's the direction I should go, working out at home with the guy who's been getting me better for the last five years. Choosing my dad and my cousin as agents, those are two guys that I can trust more than anyone." Burke said he knows some NBA teams will quiz him about that choice. In fact, he said the Pacers already had. But he joked he had a far easier time answering that than he did the interview question made famous by Microsoft years ago. Why are manhole covers round? Well, because manholes are round, for one thing. But there are several other reasons a civil engineer could give you, even if most NBA point guards — Burke included — probably can't.
