Devin Singletary is a revelation. His one cut is decisive and explosive, and he has a good feel for what is an opening in this scheme. Also revealing is that this organization does not know wtf they are doing when said player is revealed to them.
Same thing was said about the Kubiak WCO. Are we going back to the BOB days where anything good that happens is because of the QB and anything bad that happens is because of the OC?
Could it be as simple as Pierce running with his head down instead of up? I don't have access to the film, but the runs I remember he has his head down a lot as if he's looking at the defender's feet rather than their waist. I was taught ages ago that was the area that was least susceptible to fakes and misdirection.
