The structure of Matthews' contract is quite intriguing considering how it is almost entirely signing bonuses.
Auston Matthews 4 year $13.25M Cap Hit Deal:
Year 1 775K Salary, $15.925M Signing Bonus Year 2 775K Salary, $14.425M SB Year 3 900K Salary, $10.18M SB Year 4 900K Salary, $9.12M SB
Includes full No Move Clause
The contract is also front-loaded which many players want their contract to have.
The contract being mainly signing bonuses means Matthews will get the money primarily upfront at the start of each year and will get a small salary at throughout the year.
The contract being basically all signing bonuses means that Matthews will be basically buyout proof but it is unlikely that the Leafs will ever have to consider buying Matthews out.
