I'd ask him one of the following:
1) Did he think honestly at the time Boston had the best deal for Kevin Garnett, and did he think McHale thought at the time the Boston deal was the best available too?
2) Why is Kevin McHale not our new big man coach?
3) Will there be a lockout, and how is the possible lockout going to change the face of the NBA?
4) Will he ever consider coaching again?
5) Cage match, him and Tree Rollins..who wins?
You always end with a laugh.
