Yes, we have about $20M in possible restructuring left (including Parker), if we want to push another $20M of costs into the future. About $12M is needed for costs from camp onward for such things as: rookie salaries, Player 52, Player 53, Practice Squad, Players who end up on IR, replacement players for those who go on IR during camp and the season, incentives that count in the current year (e.g. game incentives).
That leaves about $8M available from restructures. More is available by cutting players or by extending them. For example, we are NOT playing Bailey over $4M, so with that savings at say $2M, we have $10M of 2022 cap money available for free agents before difficult to negotiate extensions.
That being said, there are several POTENTIAL extensions.
