We're going to have to agree to disagree. Former NFL players confirming doesn't mean anything. By NFL rule, if 68 in eligible, then 70 is not. The defense did NOT line up opposite 68, which MAKES that an illegal formation whether 68 reported eligible or not.
The referee is claiming 70 reported eligible and not 68. But 70 is saying he did not report eligible. It's a he said she said, but it is the PLAYER'S responsibility to ensure the referee knows who is eligible on a play. Especially an untimed play with the game on the line.
I love blaming the referees as much as anyone, but to remove all fault from the Lions in this case seems over the top to me. They hold some as well.
ALL that said, I STILL say the refs screwed up, as I have all along. But the Lions are also the ones that decided to go for it 3 times instead of taking it to OT.
