Everything I can tell says #68 probably did report. But because the lions were trying to get cute and confuse Dallas by having multiple lineman look like they were reporting and that caused confusion with the ref who thought (perhaps mistakenly) #70 was the one reporting. However, the audio from the stadium shows that they announced #70 as reporting as eligible before the play started. Dan Campbell or Goff, or one of the lineman should’ve caught that and realized #68 was not eligible. So they did have an opportunity to be aware of something wrong, even if it was a mistake by the ref.
Also, going for 2 on the 2nd and 3rd try is just dumb. Especially after all that happened on the 1st attempt.
