we got schemed and now other teams have copied that..
This exactly.................our run defense has been schemed and the rest of the league is following the blue print.
The inside trap where the RB can flow backside is killing this run D because our DTs are too undersized to fill the gap and that lets blockers get to the second level on our LBs. To counter, we have to bunch our DTs which allows outside contain to fail or we "press up" with the LBs to fill the gaps the DTs are getting washed out of. They either guess wrong and hit the wrong gap or they guess right but get blocked by the backside wash or end up out of position by overrunning play side and not maintaining containment on backside.
In short, its just a horrible scheme we are running with players that dont fit the scheme to begin with. We should be using huge, run stuffing DTs to clog the running lanes and keeping our LBs "clean" to flow play side. That would be a huge improvement right there. Next, stop with this stupid alignment where the DTs are split around the center and the DEs are lined up on the outer shoulder of the OTs, its like some weird version of the "wide 9" the Eagles played under Chip Kelly but we are even screwing that up.
Bottom line...................we have a bad scheme and the players we have dont fit that scheme. Either need new scheme or new players.
