I'm not exactly sure why Calderon has taken the brunt of so many fans' anger. Most players in his shoes (i.e. where every year they try and trade or replace you) would have demanded a trade ages ago or played like crap until they got traded. He's always been a consummate pro, he's always worked hard and never complained and he's been productive offensively for years. Yeah, he's not Chris Paul or Rajon Rondo but Calderon has been the least of this team's problems.
I've always felt like if Colangelo had put as much effort into finding a SG and SF as he has trying to replace Calderon, this team would have been far better off.
