Yes, most schools could easily implement electronics to signal in the plays.
Until you change the rules, which totally prohibit this kind of thing, it’s still wrong and Harbaugh should pay the price.
Just because you think the rules are stupid, doesn’t mean you can violate them when the rules still exist.
The NCAA should have gotten rid of the rule against electronics decades ago. This is on them. They made this stupid situation. They made the stupid rule.
I don’t think the rules are stupid. They ARE stupid. Outlawing scouting IS stupid.
