The issue of integrating another lottery pick into the team and the issue of balancing who takes the shots and how they get those shots are almost two separate issues for me. That's not to say that they aren't related, but we already have the second problem whether a new guy comes in or not. And that's part of the reason why this team can't seem to play up to it's talent level.
We've been fortunate enough to find a player in Marcus Thornton who was probably undervalued in the league and we've managed to lock him up for a few years at a reasonable price. Furthermore we've been fortunate enough to draft a guy in Isaiah Thomas who came ready to play and has a toughness and swagger about him which is atypical of his age and experience (sound familiar?) Independently these are great developments for a struggling team, but the net result has been a guard-oriented offense which too often falls apart late in games as our player's inexperience catches up with them.
So when someone asks about who we need to get rid of to make the pieces fit, I think you're looking at our situation from the wrong angle. We don't need to get rid of anyone (well, except Outlaw and Salmons -- addition by subtraction there), what we need to do is put together a coherent team either with the pieces we have or by acquiring new pieces. Rather than starting with a terrible team and trying to adjust it or correct it, maybe we should start with a blank slate and put the pieces who do fit into it, and re-shuffle up the rest. (Don't get me wrong, I love this team. And I see a ton of potential there. But let's not kid ourselves, it's a terrible team by any measure.)
For example, start with Cousins. He's a league leading rebounder, looking more and more like a go-to scorer, and a capable albeit limited defensive presence. That's a pretty good start to any team. So what would fit next to him? We probably don't need another high volume scorer. We should have someone who compliments his game with length, athleticism, good defensive instincts. Someone who won't get unhappy if they don't get many shots but could also provide a scoring threat when Cousins gets doubled. That could be Davis or Drummond. It could be a veteran free agent or a trade target. Heck, it could even be Hassan Whiteside. But whoever it is, how many shots they'll have per game is about the last thing you should even be concerned about. It's just a total non-issue.
The backcourt dynamic is similar. We've tried having two high volume scorers whether it be Bibby and Martin, Tyreke and Martin, or Tyreke and Thornton. It's not working. It rarely works. Thornton and Thomas doesn't work either for defensive reasons (as we're seeing right now). A lot of people seem to want to make this about picking favorite players but it's really just pragmatics. All three of these guys are valuable assets (I would even throw Jimmer into the equation as well since he's got a lot of potential even if he hasn't found a role yet this year). It's great that we have all of them -- especially since Thornton and Isaiah didn't cost us much to acquire. But that doesn't mean they all have to be Kings for life. If we can trade all of them and make the team better than that's what we should do.
And lastly, playing Tyreke at SF is just so wrong-headed I don't even know what to say about it. I predicted Westphal would do it way back when we drafted Jimmer -- though I didn't know Smart would be the culprit and the third guard in the equation would be Thomas which makes it not just a smallball lineup but a ridiculously smallball lineup. It's almost as wrong-headed as the three iso-guard attack of Tyreke/Thornton/Salmons that started out the season. We need a true wing player to man that position -- someone who can shoot, drive, defend, rebound. When we had that we were a playoff team. Obviously it can't be the only thing you have, but right now we've got a dominant big man and a variety of scoring guards. That's our roster so that's who we play. That multi-faceted wing player is desperately needed to push everyone back to their natural positions and tie it all together.
Greene isn't ready for the responsibility but putting him out there at SF every night would be a lot better than what we are doing. Getting Gilchrist, Barnes, Batum, or Wallace would be ideal.
