I respectfully disagree. Nice or not, he has what it takes to compete at the highest level. Right now he may not have the graceful look, but his body is a sculpture and he has laid a very good foundation. A tweak here, and there, and he's got a winning package.
You can't win at the top with just good form and structure, it takes sheer mass (ala Coleman, Jay, Ruhl, etc.). There hasn't been a Bob Paris or Frank Zane win in a very long time. Trends are leaning towards Mustafa's build. And he's light years ahead compared to the others at both the Ironman and Arnold. Coming to the O built like Lee or Dex will place you nicely based on flow of muscle, but won't propel you to the top tier where only the mass wins.
