I don't think it was tracked back then but I can't recall him ever being off the field unless it was a blowout, training camp or he was holding out. If it wasn't 100%, it was damn near close.
I call BS on his +1.2... He's only posted 20 rounds since 2016??? No way... He's likely only posting his best scores and I would classify him as a reverse sandbagger or a vanity handicapper
I don't remember exactly why but Donahoe brought in Mike Schneck from the Steelers and if I recall correctly, didn't Dorenbos only do punts when he was with the Bills? I seem to recall Trey Teague being the long snapper on field goals.
