Unethical or All's fair...

I honestly don't see a problem with it. It's like super advanced scouting rolled into one neat little wristband. If the coaching staff of the opposing team was smart, they'd catch onto the wristband action and start marking the information down in a notebook. There can only be so many plays until they'd start running duplicates and you could relay your own information into your players.
