I'd say we need to get Morris or Patterson from the Rockets and Eric Bledsoe from the clips.
Bledsoe would probably be a no-go with the Clippers. He hasn't been that great, anyway, so I wouldn't mind if we didn't get him.
We might be able to get Morris or Patterson in place of Hill, Dragic, or Budinger, which would be nice. But not necessarily a deal-breaker if we couldn't, as long as the Rockets included a pick or two.
Still, the thing that would bother me about the Rockets deal is the feeling that we'd be trading Pierce to a team that's not likely to contend. If Pierce is getting traded, I'd like to see him go to a competitive team (which I why I proposed a trade with the Spurs).
