Ken's article is very helpful.
It is clear GT didn't have a huge pool of money, but maximized what they could. The fact that the incentives were largely in line with what I believe the incentives were for Collins suggest this isn't a result of decreasing the guaranteed and increasing the incentives. More, this is what GT could make work with the budget constraints.
According to the AJC article Collins staff was paid $5.7MM last season.
The $10.3MM combined number (Key + staff) is the highest GT has ever paid out.
GT came into this season with $12.1MM fund deficit and then has to pay out $11.4MM to Collins.
According to the USA Today database the total paid to the 10 on field assistants in 2022 was $3.9MM. That was eighth out of eighth among the 8 ACC Schools required to report numbers (the public schools).
If you assume the same 32% increase for both on field and off field support than the new contract would move GT to sixth among the eighth (assuming none of them increase their numbers as well).
