You keep bringing up players who aren't even half the shooters Paul is. And I don't know how choosey do you want your argument but Drexler won his championship as a second option, if Drexler got to keep playing his style while being a second option, why can't Paul?
You are probably going to say "because Harden is a ball dominant player." well, 1st: so was Hakeem on the block, and 2nd, there are lots of possessions to go around. If Harden was able to co-exist, on the same team, with Durant and Westbrook, how is he not going to be able to play alongside Paul?
Also, if Wade and Lebron, who are worse shooters than Paul and Harden, made it work, why can't Harden and Paul?
