Fair question:
I think a lot of the early defensive issues were players not converting, instead of scheme. He had a number of well-timed blitzes today, two of which resulted in game altering plays. He kept his team focused and methodically chipping away despite the slow start. They’ve dealt with injuries to major contributors, playing practice squad players and defensive tackles at DE. They had untimely turnovers on offense, and bad weather, coming back in the second half down multiple scores when other teams would have folded.
Allen helps a lot, no doubt.
