Is it not a good idea to work out secret schemes with your player or even use wireless ear-sets like they do in the NFL.

Of course I am being half funny half serious but if it is legal is it not OK to exploit it ?

After all the New England patriots were reading the signals of opposing teams (& every year they come up with different interesting ploys such as ball deflation etc etc which is sort of half exciting because the whole NFL wonders what scheme is going thru the head of Bill Bellicheck this year). Heck Sean Payton , the coach of New Orleans Saints put out a bounty scheme (on who can actually injure opposing players not for just one game but as long as possible, I think).  Just saying
