Wes - where are you getting your salary info from?
There was a more detailed article in the post at the time talking about Frank's 10% bonuses of his base salary for winning a bowl or the MAC and 5% for winning the MAC East. His contract states 400,000 of guaranteed income and people are usually prorating his retention bonus (75k a year) on top of this to calculate his compensation (stated as 475k on the contracts site). The 460k figure listed by the other poster likely included the bonuses but excluded the retention bonus so counting retention Frank was 535k last year and 556k this year for 9 wins and an East title. If Frank can win a bowl that is another automatic 10% plus hitting 10 wins would bump him to 600k on the season.
