Kaler's salary vs. his old Stony Brook pay, Bruininks' pay

Quick math:

Bruininks’ pay as of this fall was $455,000 base pay, $650,000 with benefits.

Kaler’s base salary is $610,000 (close to double his old Stony Brook base of $347,000.) Starting in his second year, Kaler will theoretically get $660,000, including his $50,000 retirement benefits. But I haven’t read through his contract yet.

Does anyone with more business acumen than I have any suggestions about what elements to compare?
