In my opinion, Dabo isn't going anywhere. He's not that foolish. Saban ran back to the college game in a heartbeat after facing the realization (at Miami) that he no longer had an overwhelmingly advantageous talent discrepancy. Just as Saban, Dabo has the luxury of fielding a team year in and year out with a huge talent advantage in the league his team plays in, as well as nationally. Additionally, as Saban, Dabo has an annual contract that bests many NFL coaches contracts, not to mention his endorsements. Clemson's facilities are also second to none as well and better than many in the NFL.
Why be the piss-boy in the NFL, when it's good to be the King!
