I agree. I think sign stealing is a part of competition. But I do think there are limits to sign stealing too.
In the traditional sense … I’m trying to decipher your signals … I’m fine with it. And the reason I’m ok with it is … well, you look for gives within the game as it is … positioning, eyes/looks, it’s all cat and mouse and I consider signs the same way. If you misinterpret … it can backfire big time, so there is risk, too.
Using different camera angles, sensitive mics, electronics or non-team personnel to convey things back, no, not a fan. At all. That’s cheating.
It should be “natural” or at least “traditional”.
