Once the coaching staff is cemented in place, the next frontier will be free agency. According to multiple sources, the Houston Texans have $37 million under the cap they could theoretically spend on free agents. Naturally, that number is fluid for any number of reasons.
Teams have to leave a certain amount aside for the draft. So, that $37 million becomes closer to $30 million when all is said and done. However, there are cap capsulitis every year. Teams can sometimes cut as much as $20 to $30 million from their cap by either cutting veterans or restructuring their contracts.
