The bulk of that salary is already accounted for though by the fact contracts are staggered based on what cash they'll have available in any given year. Martins money has already been used on other contracts from 2024 onwards.
Martin goes from $1m to 1.4m in 2024, and that cash will go to Lynch's contract in 2025 where he will go from something like $800k to $1.5m during that time.
Once Lynch's contract ends in 2025, that cash probably goes to Bolton who will go from $500k to $900k for the start of his new 5 year deal and so on.
The only cash freed up from Martin leaving will be what we have reserved to sign him up for after his deal ends, so if we think we'd pay Dusty $5-600k over maybe a couple of years to stay then that is what will be freed up, not $1.4m
