I just don't see the need. I cannot fathom what about Darko makes him better than Collins or what we already have.
I would have preferred Birdman over either Collins or Darko, but this is a solid gamble on a player with legit defensive skills.
Me too -- Birdman over Darko.
Chris Andersen brings more diversity to the backup big man options for Doc Rivers. A different type of skill-set as a mobile defensive five / possession creator. Something none of the other bigs on the roster (outside of KG) offer.
As bucknersrevenge said, I don't see what Darko does that Jason Collins doesn't bring to the table.
Collins is the stronger post defender, overall man-to-man defender and offers similar (if not superior) team defense. Both are very limited offensively (liabilities) and both are weak rebounders (Collins worse than Darko).
I am not seeing a reason or situation where Darko offers more value than Jason Collins does. I can't see a reason to play him ahead of Jason Collins.
Still, having another big body has it's uses. Another big lug with 6 fouls that Doc can throw at power-based centers is useful ... but it felt like there were better options out there (Birdman being one of them) that would have offered the team more value.
