Filler is, in my view, exactly as skilled as Earl Strickland was in his prime, but Josh is a more complete player than Earl was, because his decision-making and defensive play are a little above that which Earl displayed.
You don't think decision making and defensive play are skills? And that they are part of a person's overall pool skills and abilities? Really?
Maybe we are defining skill differently but for the world of me I can't imagine how you could possibly be defining it that would not include their decision making and defensive play as being part of their skill for the game, part of what makes their ability what it is. When I say skill I am talking about their ability to play, as in how good of a player they are. As in if you could time warp them when they were at their peak into the same place and have them play say three races to eleven every day for a month, who would have won the most sets at the end of the three months?
Varner and Sigel were, ever so slightly, better players than Strickland, but neither had more skill than Earl. If titles is to be the tiebreaker between equal talents, Earl Strickland still rates above Filler.
I don't know your age, so I don't know the extent to which you watched Strickland in his prime, so forgive me if I'm telling you what you already know. Earl, especially in 1984-94, used to whitewash champions of the highest order on a regular basis. It was mind-blowing how often Earl beat guys like Mike Sigel, Nick Varner, Jim Rempe, and Buddy Hall by very lopsided scores like 11-1 or 11-2 and how often he won major titles going undefeated from start to finish. Just like Filler, he mass produced major titles, including five US Open 9-ball titles and three WPA World 9-ball Championships.
I feel strongly, however, that Filler's career will one day eclipse that of Earl Strickland, not because he's more talented but because he's a more rounded player. I must admit that in my years on the forum, this is the first time I've found a poster that thinks more highly of Filler than me. Ultimately, we're in the same camp, and we both understand what we're watching when we watch this remarkable player.
Once again you are going by their records and accomplishments instead of just comparing their games and what you are doing is analyzing who the "most accomplished of all time" is, not who "the greatest of all time" is. It really is as simple as I laid out in a previous post. If there is or ever was anybody that could have said "how can you be the greatest of all time if you didn't play better than me and wouldn't have been able to beat me" then you are not the greatest of all time, period, end of story.
As in if you and my (just to pick any two players) prime selves were to play three races to eleven each day for three months, and I would come out on top, then I am a better player than you regardless of what titles you have won or anything else.
How can you be the greatest of all time if you can't beat me? Don't you agree that you can't be the greatest of all time if there is somebody else that plays/played better and would (have) beat you? Clearly you aren't the greatest of all time if that is the case although you could certainly be the most accomplished of all time, or the most dominant of your era, or something else, but those are very different things from the greatest of all time.
I've been around for all of the players you mentioned. Something that is important to know though (and to do something about) is that all humans have a natural tendency to let how good players of the past played in comparison to their contemporaries skew and inflate how skilled we view them as having been when we try to compare them to those from another era. Among other things I think you still have a tendency to fall victim to this a bit as well. You really have to fight hard to not be influenced by how much better they were than the others from their era and isolate their game away from that and see how their game alone in isolation would stack up against someone else. For example, we have to completely forget how much Strickland dominated others in his prime (part of the time anyway), and we have to forget how much Filler is dominating those in his prime (a good part of the time anyway), and just compare their isolated games and games alone and determine who was more skilled, as in who would have beat who if they played three races a day for three months in their primes. How much they dominated their peers in their time, or how many or what titles they won, and anything else simply isn't relevant to that (unless/until they are tied in skill/ability and you need something a tie breaker).
For the record, if we time warped Earl in his prime and Filler in his prime and had them play 3 races to 11 every day for 3 months, Filler would win, because Filler is more skilled, the better player, however you want to say it. Therefore it quite simply is not possible for Earl to be the greatest of all time because there is somebody else that was better than him (how can you be the greatest of all time if you can't beat me?). I also think Filler in his prime beats SVB in his prime as well, and some would argue that they are both currently in their primes and Filler is doing just that in real time and we are getting to watch it, but my opinion is that SVB while still very near is just past or at least off his prime.
Sometimes it is real hard to figure out who would have won in their primes though and it is too close to a tie to be able to tell, like maybe you can't figure out who would have won at the end of three sets a day for three months if Sigel and Hall were time warped from their primes (just an example, pick any two you have a hard deciding who would have won between), and that is when you now have to start looking at things like titles and other factors in order to break the tie in the pecking order for GOAT. Your ability as a player is what makes you the greatest of all time, but there is plenty of room for debate on what things should be used as tie breakers and how much weight we should give each of those things when two players are equally skilled/play at the same level as we must use some secondary criteria/s to break the tie.
"How can you be the greatest of all time when there was somebody else more skilled than you, that played better than you, that would have beat you?" You can't.
