I wonder about that Nick Collison vs Matt Bonner matchup. Or even switching Collison off Bonner and having Horford or Aldridge play Bonner.
I think Matt Bonner's three point threat and how he opens up the offense will create more added value for his team than Collison would add as a defender/rebounder out on the perimeter covering Bonner.
Even if you switch Collison and have Horford or Aldridge defend Bonner, their (Horford or Aldridge) defensive contribution would drop off in that matchup too. I think the net-gain by switching the defensive matchups would be fairly small. And I think it would need to be Horford on Bonner. I don't Aldridge defends perimeter bigs well enough.
I think the Lakers would be better off following the Thunder's idea of going small against Bonner to both neutralize his three point threat + create an offensive advantage going the other way. Put Rudy Gay at PF against Bonner. Bonner would have to defend Carlos Delfino (SF) which he can't do.
And Delfino is a more capable (shooting ability, ball-handling ability, driving, shot-creation, passing) vs Bonner (strictly a spot-up shooter) ... which would make Bonner a liability for Portland. Give LA the matchup advantage there.
