You need to pick your spots. I've coached many sports and teams, you don't argue untill it's really important, this shows JM's intensity towards Minny. As a wrestling coach and former ref, when your worst athelete gets screwed, don't argue, when your best athelete gets screwed freak out, that's when it matters and refs will pay attention because you are really upset. Hockey...badger every call, the ref could give a s***, argue pationately in the 3rd when it matters he knows in the back of his mind...I could go on for managing baseball and other sports, but really I believe that you have to pick your spots and though Manuel is even more selective than many, the umps will pay more attention because it is more rare that he argues. Hope that all made sence, sorry for the ramble.
