Re: Texans cap space
The NFL cap this year is 123 million, but the Texans carried over 2.4 million in cap space, so they have 125.4 to work with this year. If the Sportrac numbers are right, they have 49 players under contract for 112,540,856. They have 2,130,742 in dead money, but Walter's hit may be a June 1st designation, which would mean it's only 1m counts against the cap this year.
Assuming all that is correct, they should have $10,728,402 available (give a mil if Walter was June 1 cut), before filling the other 4 roster spots, practice squad costs (816k this year), and signing rookies.
