...and yet so often those fat guys in arm chair are just using extensive knowledge of their sport coupled with basic common sense and those leading the teams often make huge mistakes that they themselves admit to.
Blind calls by refs, poor player substitutions, stupid play calling, etc. Sometimes an outside pair of eyes can more readily see the mistakes being made than those in the mire of it all.
As with so many of the complaints being made here, its just simple observation made without the blindness of fanboi goggles.
Yes, that's why those fatguys are the well-paid professionals, right? Because of their well-honed knowledge gleaned from watching professionals do their jobs.
