Clemson is well known as having mastered stealing opposing offenses’ signs. Hence, ND huddled against them earlier this season. This was a good article about it in SI. https://www.google.com/amp/s/www.si.com/.amp/college/2020/11/06/clemson-...
Sign stealing is a part of all sports. Clemson isn’t the only team that does it by any stretch. All teams, including our Buckeyes, I’m sure do it. But as we know from the Patriots to the Astros there’s a “legal” way and a cheater’s way. From this SI article, it seems Clemson spends a lot of resources - money, GAs, analysts- to steal signs. One can’t help but wonder if that’s all.
If we meet them again, counter-measures must be part of the game plan.
