"We've got some serious problems that we've got to address," coach Gary Kubiak said after the Texans ended their season with eight losses in their final 10 games. "It definitely wasn't all coaching, in my opinion. We've got issues across the board. I had to make a decision on how we can get better, and so doing that, I made that decision to let those four guys go."
Joseph will be counted upon to help a pass defense that struggled all season, yielding an average of 410.5 yards per game through the first six games. The Texans started 4-2 only because the offense topped 30 points in each of the victories.
