You are not even in the ball park. Yes players have bad days but coaches make the decisions to win the game as they see fit. The player at habd is a rotation players with his backup. I start the one who is more appropiate for the gam becasue i cant have a startering lineup knowing the fact my coach will make the right decision. So if i make a mistake like i did here then it can be fixed by the head coach.
For the record the best head coaches have thos ebrave assitants to help them make the right decisions. That is why when you watch profesional team play they usualy have the same starters every night and make the rest of the decisions based on how the offense or defense is playing the paticular night. Then he decides if they are having a poor night and is it worth waiting for them to wake up or give him a few moments.
You got to know when to hold em, know when to fold em, Know when to walk away and know when to run. You never count your money when youre sittin at the table. Therell be time enough for countin when the dealins done.
