The U.S. men’s basketball team has been “bullied” in the past because of the size of the players.
Generally speaking, Coach Kerr played smaller lineups, and in losing three of their final four games at the World Cup, the U.S. was often gutted on the glass and in the paint.
From NY Times "For the Olympics, USA men’s basketball has a sizable fix to fight a bully problem"
Can anyone explain “gutted on the glass and in the paint”?
