Watching OKC and Indy this past week I came up with the following trade idea. It is obviously continent on PP and KG not coming back and the Celtics moving into an asset building mode.
OKC gets Paul Pierce
OKC losses Perins, Martin S&T 9mill, (either 2013 1st from raptors or Jeremy Lamb)
Indy gets Kevin Martin (S&T 9mill), Jason Terry
Indy losses Granger, 2014 1st (top 20 protected)
Boston gets Perkins , Granger,OKC 2013 raptors pick or lamb, 2014 Indy protected first.
Why it works
OKC, they clear out Perks contract and fill his spot by giving thabeet and colison more minutes. The addition of Pierce makes them a scary playoff match up. The emergence of Jackson should allow OKC to confidently let Martin go for a more short term upgrade in Pierce. If the 2014 season ends with a OKC vs Miami matchup a line up of Westbrook, Jackson, Pierce, Durant, and Ibaka may be the leagues best chance at beating the Heat. After that Pierce is off the books and they are in a safe place cap wise.
Indiana, the pacers gain two veteran perimeter scorers without losing anything from this years team. Hill, Stephenson, Martin and Terry will give the Pacers a very solid 4 guard rotation to pair with the rise star of George and a tough inside team.
Boston, the team will take a step back with this trade. Granger is a shell of himself with his bad knees but he is an expiring deal. He could be traded at the 2013-2014 deadline either as a usable player to a contender or as cap relief (either way flipping him for assets). Perkins is over paid but still affective he will be able to continue the tough defensive identity that Garnett has brought to this team. This will also be a deal Rondo likes. Perk's contract will have 2 years left on it, which isn't terrible for a team regrouping. The addition of Toronto's pick(#12) or Lamb should be valuable as should Indy 2014 1st.
For Boston as I have posted before my end game plan would be to use Celtics 2014st likely lottery if RR misses time, Indys 1st (20-25), Avery and Bass (or Sully and Lee), along with Grangers expiring deal to get LaMarcus Aldrige or Kevin Love. This would be a similar situation to how DA brought in KG.
