The NFLPA released the official salary cap figures for all 32 NFL teams. Houston finds itself in the middle of the pack with a cap of just over $187 million, some $10 million over the official NFL cap figure.
The figures vary from team to team based on carryovers and adjustments due to things like retirements, settlements and contractual restructures.
Per Troy at Texans Cap, the Texans should have right around $62.3 million to spend this offseason. That figure does include the rookie contract pool.
