Nick Saban, who led Alabama to this past season's national championship, is set to become the highest paid football coach at a public university at a little more than $5.3 million for the 2012 season.

Saban's new compensation package was approved unanimously Tuesday by the compensation committee of the University of Alabama System board of trustees.

Saban's agreement also was extended by two years, meaning he is under contract through the 2019 season. The total compensation of the deal is just under $45 million, not including potential incentive bonuses.

For 2012, the deal involves an increase of more than $630,000 over what he was paid by the school for the 2011 season. It is an increase of a little more than $550,000 over what he had been scheduled to be paid for 2012.

Pending adjustments to other coaches' contracts, the additional pay will move Saban past Texas' Mack Brown as the highest-paid public school coach. Brown received slightly less than $5.2 million in 2011, according to USA TODAY's survey of football coaching compensation, and his contract calls for annual pay increases of $100,000. Brown's contract was extended by four years through the 2020 season in January without a change in his pay structure.

Saban is guaranteed a $50,000 increase for 2013 and then $100,000 increases in each subsequent year, reaching just under $6 million for the 2019 season.

Also on Tuesday, pay increases for Alabama's incumbent assistants were approved. Defensive coordinator Kirby Smart's compensation increased to $950,000 per year over the life of a three-year contract.

New offensive coordinator Doug Nussmeier was give a three-year deal worth $590,000 per year; previous offensive coordinator Jim McElwain, now the head coach at Colorado State, made $510,000 in 2011.
