Can you name the athletes by the picture?

A business man got on an elevator.when he entered,there was a blonde already inside who greeted him with a bright ,"t-g-i-f"
He smiled at her and replied,"s-h-i-t"
She looked puzzled,and repeated,"t-g-i-f".
More slowly he answered,"s-h-i-t"
The blonde was trying to keep it friendly,so,she smiled her biggest smile and said as sweetly as possibly,"t-g-i-f"
The man smiled back to her and once again"s-h-i-t".
The exasperated blonde decided to explain what "t-g-i-f" means "thank goodness it`s friday",get it duuhhh?
The man answered"s-h-i-t" means "sorry honey it`s thursday."
