This position play ability is one of the things I look for to see if a player is a D/C or B/A. If a guy runs out a rack and they are out of line half the shots, they may be a C and got lucky, if they run a rack and they are out of line on maybe one shot, at least a B-.
If you run out 6 balls or even 5 but are in position on every shot or close to it, you are not a C player anymore.
C players should not be able to do 6 ball runs 40% of the time, maybe 25%. A C is just a level over a person just past a beginner that can make 1-2 balls (D player), no way can a C, one level over that, do 6. C players are in the 4 ball range, 3/4/5 C- to C+. If we call C players those that can almost run out a 9 ball rack if they make 2 balls on the break, what do we call a B or an A?
I don't have a scientific method of rating them.
I have seen a couple of charts that attempted to rate players, they seemed to rate them lower than I did also.
The problem is ,they try to squeeze 100 levels of abilty into 6 or 8 brackets. Lets say Orcollo or Shane are the best nine ball players in the world. They would be Super Pro
Then there are 10 guys they can't give anything to or they will be the underdog.
Then there are 50 guys they can give the last 2 but not the 8 , and on and on .
There are guys they can give the 7 ball to, who I would rate middle Pro level.
Then a whole other animal comes into play if gambling , you have to factor in, if the guy can fade a big bet or not.
Many cannot, especially if it is their own money.
Also, Some guys just can't play tournaments.
I think it's the hustler in them saying , "this is bad for business."
The only reason I ever even thought about it was for gambling purposes, there it is not a bad thing, if you tend to overrate the opponent, and underrate yourself , because the reverse is what keeps most gamblers broke.
