Tough call
DE is a bigger area of weakness, we cut 2 starting caliber DE's in Red and Clemons, and Schofield was also so decent depth that is gone/will be gone. Unless you consider Irvin our #3 DE we really don't have a guy worth penciling in there yet. I think Adding Allen to the Avril, Bennett rotation would be perfect and and we would have the best 3 man DE rotation in the NFL. Allen has some gas left I think 2 really productive years at least if he plays here in a rotation. His numbers would be pretty good with the home field advantage we provide and the LOB helping coverage sacks.
DT isn't as big of a need because we have 3 guys in Scruggs, Hill, and Williams who have either flashed skills or were draft picks high enough that JS thought they could step into a starting role at some point. So adding a DT isn't a big need but Melton is on the border of being an elite pass rushing DT and getting him on a multi-year deal for anything less than $7-8mil a year is a pretty good deal. His addition would allow Bennett to stay outside in more pass rushing situations and provide a know commodity of passrush right up the gut which is key to getting the qb out of the pocket and sacked.
So skip forward to feburary 2015 and we are in the Super Bowl playing Den, NE, or Baltimore. On 3rd down would you rather have Avril, Mebane, Melton, Bennett rushing the QB or Avril, Mebane, Bennett, Allen?
It's very tough but I have to role with Allen who I think is a little more expensive but less risk. It's not likely we'd get Melton for more than 2 years, and worst case is Allen only has 2 years left so looking further out than that isn't necessary.
Bring on Jared Allen, but if we could get both look out
Avril, Melton, Bennett, Allen rushing a QB's at the CLINK would force the NFL to create some new rules, liek a 2 second head start because QB's would be getting crushed!
