Financial implications of the decision to cut Shaq Mason (from the Chronicle)

The team is designating Mason a post-June 1 cut, which means they will save $9 million in cap space, the source said.

However, that money cannot be used in free agency.
Had the Texans released him as a pre-June 1 cut, that would have only save the team $2.1 million in cap space, which it could use in free agency.
