Is Wynn worth it?

[Defensewins]

I dislike that in today's NFL, a DE's value is mostly measured by how many sacks he gets.
High price pass rush DE like Simeon Rice and Jevon Kearse usually get knocked on their ass on run plays. Where is that stat? Where is the stat of how many times a pass rush happy DE takes himself out of a run play by taking a wide path to the QB and missing his gap responsibility and the Rb all together?
The fact is the sack stat is a high glory high money stat. Sacks ARE very important and the mark of a good defense, but it should not be the MAIN measuring stick of a DE.
It amazes me that out of the top 10 sack leaders in the NFL in 2005 regular season: only one (Dwight Feeney was on a superbowl contender and did well in the playoffs), although their defense was their weakness. Proof that having a high sack DE is over rated?
