This is just pure speculation, but I find it very interesting that the plane Tom Izzo flew to Cleveland on yesterday is now headed to Boston. It's interesting because Byron Scott, the other serious candidate for the Cavs job, is in Boston to cover the NBA Finals. It could all just be one big coincidence, but I'm willing to bet that plane is for Scott.
The Cavaliers need to have a plan in place in case Izzo decides to stay at Michigan State, and right now Scott is that plan. He interviewed with the Cavs for an hour on the phone yesterday, and perhaps today is his official interview. I don't know if the plane is going to pick up Scott and take him to Cleveland or what, but it is on its way to Boston right now.
