The bottom line is he's not going to produce that many points as a 3rd or 4th option because, as demonstrated, he needs to put up a ton of shots to get his points. Based on his NBA career so far, he will need to put up 14+ shots per game to get those 15 points -- that's more shots than anyone on the Boston Celtics roster took in 2007-2008, for example.
Bradley being a 4th option is kind of a joke anyways. Like D.o.s said, if Bradley is the 4th option, who are our first 3 options?
And putting up 14 shots per game to average 14.8pts at a .441 FG% is really not a negative factor. Especially when he had an even better FG% before his shooting slump in the month of January.
Besides, somebody on the team has to shoot, so it might as well be Bradley. His offense is steadily improving, and his jumpshot is more solid than almost everyone else's on the team. This isn't 2007-2008, when we had 3 perennial all-stars all sharing the ball as our top 3 offensive weapons. Nobody needed to take 14 shots per game that yr. There was plenty of top notch shooters to share the ball with, even the bench players like House & Posey.
I wouldn't mind Green leading the team in shots this yr either, but he just doesn't seem interested in doing so. He passes up a lot of good shots, and isn't always aggressive enough...Even though he usually has great games when he is aggressive, like in Orlando the other night.
