When Kris Humphries embarked upon his NBA career with the Jazz in 2004, he looked up and saw Carlos Boozer and Andrei Kirilenko ahead of him in the rotation. He was traded to the Raptors in 2006, just in time to sit behind Andrea Bargnani and Chris Bosh. In 2009, he was traded to the Mavericks, where Dirk Nowitzki reigned at power forward. “I’ve been in tough situations in the past,” Humphries said. “If you remember when I came to the Nets [in 2009-10], I wasn’t really in their plans. They drafted [Derrick] Favors, traded for [Troy] Murphy, signed Joe Smith. I was playing with the fourth or fifth team in training camp.” The key word there was “playing.” Over the past four games, Humphries has been glued to the bench as the Nets employed Mirza Teletovic as the backup power forward to Reggie Evans. But interim coach P.J. Carlesimo apparently has seen enough of Teletovic’s defense and his .362 shooting — not really swell when your rep is that of a shooter — and has indicated he wants Humphries back in the rotation before the playoffs.
