Watt only made matters worse by trying to play through his back injury during the first three weeks of the season. He's now done for the season after going under the knife Thursday.

Houston currently ranks second in Adjusted Defensive Net Expected Points per play, but we can expect that ranking to fall significantly with the loss of their most valuable defender.
