This sounds like the best answer to where we stand right now on the Burke situation. Guess this means they will definitely keep Cotton whether or not Burke remains on the team. But the fact that we are keeping two other backups for Exum tells you all need to know about the FO's opinion of Burke.
Exactly. Exum is numero uno, no doubt. So if TB was thought to a solid lock as the number 2, why would you keep a 3rd and a 4th? The only reason you do is that you are likely to get rid of one, and that one is likely TB from my point of view.
