Is Miles' new contract a good deal?

If I'm reading everything right concerning Miles' new deal, it appears that LSU is the only party that has incurred additional liability for a breach of said contract.
Terms of new deal:
1. Miles' salary is basically calculated the same as before (SEC Champ raise, N.C. raise);
2. Miles' gets additional money to spread around to assistants if players hit certain academic benchmarks ($150,000 to $250,000 to disburse to his coaching staff to reward them);
3. Miles and LSU extend Miles' employment for a few years (The contract had been slated to end Dec. 31, 2010, but the extension moves that to Dec. 31, 2012);
4. the contract termination clause was changed. If LSU fires Miles without cause, the coach could be owed as much as $15 million, up from $10 million;
5. Here is where the rubber meets the road: what is the "Buyout" for Miles, if he decides to leave
for any school and,in particular, Michigan. If this clause remains the same as the old contract,
LSU has really not accomplished very much with this new deal, other than create some positive PR,
which is a much needed thing for LSU right now.

Here's what bothers me: If Miles' buyout remains the same as old contract, the risk of losing Miles remains the same (yeah, yeah I know about the Miles pledge. I believe him. This post is strictly a review of terms, not a question of credibility).
If Miles starts digging a hole he can't get out of (the program starts losing), there is no way to stop digging. Where the hell is LSU going to get $15 Million?

Maybe there's something in this new deal for LSU that the press hasn't released. Guess we'll wait for the "New Deal" to be released to the public to
see what we just renegotiated ourselves into.
