there are a difference between pro and world class players that we the amateurs sometimes cannot recognize.
about consistency, world class players are capable of player several matches without committing any error, a pro can't or seldom able to do so.
about skill, YES SKILL, a world class pro, especially Dennis Orcullo, master all shots in all conditions, Orcullo can make a shot by slow roll, or with extreme draw, follow, left english, right english, when he's jacked up or frozen on the rail a.k.a any possibility you can think of. That marked a huge difference especially when the pressure kick in. A pro can have a godlike stroke etc, but he is not at the same level of shot mastery as those world class players. It's not about how far you can draw the CB, it's about draw it 1 foot back when you have to.
To this matter, Mika Immonen once said that it's unbelievable how Orcullo can hammer the ball in while putting english on the cb to get position when the cb is frozen to the rail, and then Mika admitted he should practice more those shots.
last but not least, mental toughness, some are born champion with forward and positive thinking, some are just can't win over himself.
