re: Did Clemson have Bama’s signals in 2018?

I wouldn't be surprised. If there is any viable evidence to suggest that they have done it in the past, I think it would be safe to draw the conclusion that they did it to Bama in 2018. However, I err on the side of Saban's philosophy a bit: it doesn't matter if they know what we are going to do because we just execute better than them.

Sure it may give them the competitive advantage, but what happened, happened. We have plenty of other championships to enjoy
