I also wouldn't consider Joe Johnson very efficient. I could see Josh Smith playing #2 or even #3 in an offense, where I can't say the same for Joe Johnson.
Johnson was a pretty effective #3/#4 option for the Suns before he came to Atlanta. I think it's more of an ego issue than an ability issue with him.
Not exactly sure what you mean, but I believe I agree. What gets in his way is absolutely ego, the same ego that had him going to Atlanta to be a franchise player in the first place. At this point I don't think he's willing to be anything but a #1 option.
Yeah I think we agree - I can't see him being a #3 guy at this point either, but it isn't because he can't be efficient enough to fill the role, it's because his ego won't allow him to not be a #1 guy.
I'm not sure I agree though. As I recall his decision to leave the Suns had more to do with hard feelings lingering from contract extension talks the season prior. Sarver's negotiation tactics are now infamous. That and the larger, front loaded offer from Atlanta.
His roll and minutes in Atlanta's new motion offense are reduced from season's prior and I've yet to read a negative response from J.J.
EDIT - Although, yes, fair to say he's still the first option there.
