The D coulodn't stop the run. Drew blew chunks, as did his offensive mates. Dillon ate up 74 yards against our D in the first quarter, and we barely managed to slow him down after that (and allowed Faulk to gain over 60 yards).
If DB played the way he did but the D shut down the run, I'd say about 80% with a healthy 19.9% at WM and the running game (to include the OL).
Since the D was worthless against the run AND the pass, they singlehandedly took us out of our gameplan, therefore, they get the lionshare of the blame. I'd say about 40% D, 30% WM/running game, and 30% DB/WRs.
