They need to find Michael Bennett a sub for this stretch run or the defense will suffer. Seattle needs to make a deal for Chris Clemons or someone that can do what Clem did. A DE that can hold up in the run game in base defense and rush the passer so Bennett can get his rest. Schofield, Irvin, and Avril are all good 3rd down pass rushers but they get blown up alot in the run game. Bennett is playing lights out with everything he's got and i don't think you can depend on his body to keep up with the way he plays. So Seattle needs to find a LEO that can set the edge to help out the rotation at DE.
Two that come to mind Chris Clemons from JAX or Kendall Langford from STL. either could be cheap from losing teams looking to get younger.
