If Phillips is really this naïve then we have a problem in the ACC.
This alliance thingy sounds nice but it reminds me of the "joint declarations" that one might see from the UN where each side pledges to do X,Y,Z, and there's absolutely no repercussions, fall-back, or consequence should one side break the "agreement". And that's when wars get started.
If the SEC approached FSU or Clemson or USC or Oregon tomorrow, I'll lay odds that none of them will say; "Not so fast my friend. We are part of the alliance and cannot entertain your $100 million offer to join. Not now, not ever"! Yeah...right.
