AST:TO ratio isn't really all that useful when you're talking about a list of players who are never asked to create for their team mates.
Yeah but it's a great way to rip on a former 6 year veteran Celtic guard.
If you're dealing with a player who isn't asked to create for his team I think you should look at TOV%. How often he turns it over is more important than his assist ratio. Usually a poor AST/TO ratio also means a really bad TOV%, but not always. (think Rasheed Wallace his AST/TO wasn't all that good, but he almost never turned the ball over so it wasn't a big deal)
A high AST/TO ratio is a good thing in any player, but its way down the list for someone who doesn't handle the ball at all. (which all the players listed fall into)
