I would ask what Peyton Manning thinks about that reasoning. Pretty sure he a had a presser just to say he was coming back and shock everyone!
I would think as a kid (and even if you are not that hyped up) you DON'T want to have a presser unless you are only coming back. Too many negative feelings in the room if you announce a departure. You want to be around encouragements.. not bombarded by the media criticizing your choice. Only coaches would be able to handle that IMO.
Having the ANNOUNCEMENT on the Steven Pearl show sounds like McRae doesn't want media involved or make it a huge deal....especially if he decided to declare. That's my gut feeling. Its a safer environment for him. I could be wrong but because of this scenario I'm going 85/15 he's gone.
