The scheme was working in the first half before the injuries wiped out the LBs.
That is partially true, in the first half they were taking chances, blitzing, playing man coverage, and it worked. In the second half, Kiffien decided to go with his stupid Tampa 2, come and get us, defense that he is known for, and they couldn't stop anyone. The players on defense got discouraged and gave up. They took the cue from their coordinator.
I don't know what it is with this coaching staff, when something is working great, they decide to go away from it. On offense, the running was killing GB, and they stopped running in the second quarter. On defense, applying pressure, blitzing and playing man forced 4 punts and 1 intercetion in the first half, so naturally, you go away from it in the second.
I would rather the defense get burned by blitzing and playing aggressive, than sit there and get abused by an Arena League caliber QB.
