Alex English, George Gervin, Allen Iverson, Adrian Dantley, Carmelo Anthony, etc. etc.
NBA has been littered with these type of "superstars" who are all about getting their points but did nothing to make their team mates better or overall teams great. They are the exact type of "superstars" you do NOT want on your team because they will never lead your team to a ring.
I would rather wait to see Sullinger or some future draft pick turn into a superstar or get multiple "stars" that can work in a team environment than to have a "superstar" like Carmelo Anthony.
