That’s a very worrying comment if it’s true. The very, very least any player at any level, even if he’s totally out of his depth, should contribute is effort. It’s not a skill, it’s not something your blessed with at birth, it’s not something only a few select individuals possess...it’s a basic requirement of any activity you do, and you can put in as much or as little as you like. For a world renowned coach to say that means simply that the players he has are not suitable to wear the shirt. If they can’t give effort they should be fired just like they would be in any other profession.
