Perhaps, but you can't compare some of the teams that both Barkley and Ewing had to what Steph has had. Oh he's had a few decent teams, but they've all been teams with a guy who would eventually become a stud, but it was early in their career. KG, KMart, Amare. Heck even on this team with Curry & Frye. If we keep him and this team adds the needed help and those guys develop we may yet see success for Steph in NY.
Well, let's examine: Did Ewing ever play with a player as good as Garnett, Marion or Stoudamire? Allan Houston was the most help Ewing ever got and Ewing was breaking down at that time. The Oakleys, Masons and the Starks of the world became much better players from Ewing's presence.
Barkley played one season with Dr. J, he had a pretty good team in Phoenix (KJ, Majerle), but the best help he ever had was when he played for Houston with Hakeem and Scottie, but Barkley was well into his twilight.
In any case Marbury can't hold Ewing's or Barkley's shorts so the comparison is not apt. Those guys made the players around them better, and were already in the Hall of Fame for all intents and purposes by the time they were Marbury's age.
Marbury's ego has screwed him out of having good teams. He had a pretty good team with Jayson Williams and Keith Van Horn, but his big head ruined that (Literally, by breaking William's leg with it.) and by running Van Horn out of town--twice.
