I don't think Josh has a problem playing 2nd fiddle. I just don't think he wants to spend his prime(next 6,7 years) playing 2nd fiddle to Joe and Al. Both players that Josh feels hes better than and will better than for the next 6,7 years. If it's 2nd fiddle to Deron Williams, Dwight Howard, Derick Rose, Kevin Love, Chris Paul, Lebron or Kyrie Irving for that matter then ok..
Back to the subject of Pau. I personally don't think Josh Smith will get traded cause the hawks don't NEED to trade him this season. Plus the Lakers are not a team known for taking on undersize players(unless they gonna play him at SF). Plus didn't they turn down a Rondo deal. If they turn down a rondo deal I doubt they turn around and get smith.
