I feel like I've read things where Demoff structures contracts as "pay as you go." That's pretty consistent from what I've seen with contracts from him, I think.
What might this look like with Donald?
From a CBS Sports article:
"Pay as you go
Pay as you go is a relatively new structure teams are starting to embrace. A player's cash and salary cap numbers are the same in each contract year because he is receiving salary guarantees instead of a signing bonus under this model. The first contract year usually consists of a fully guaranteed base salary and a roster bonus due a few days after signing. The second year in the most lucrative pay-as-you-go contracts has a fully guaranteed base and a conditionally guaranteed early roster bonus similar to the conditional salary guarantees in the signing bonus/salary guarantee structure.
There may also be conditional guarantees in the third year. Deals with this structure have higher cap numbers, particularly in the early years, because of the absence of a signing bonus. Since there isn't any signing bonus proration, teams have more cap flexibility. A team won't have any dead money (a cap charge for a player no longer on the roster) if a player is released during the latter years of the deal once the guarantees have expired, provided that his contract hasn't been restructured."
From later in the article it suggests that we were using a Signing bonus/salary guarantee model though along with the pay as you go.
"
St. Louis Rams: The signing bonus/salary guarantee model is used most frequently, although
Chris Long has a-pay-as-you-go deal. Signing bonuses are typically kept under $5 million with fully guaranteed base salaries in the first two years. Some deals have early roster bonuses (usually before the fifth day of the league year) that can become fully guaranteed. The Rams are comfortable with guarantees that don't have offsets. Fortunately for the Rams,
Cortland Finnegan's $3 million 2014 roster bonus guaranteed for skill and injury when he was released has an offset. The Rams will get the $3 million back from the deal he signed with Dolphins."
