Mark Warkentien's days with the Knicks as their player personnel director are numbered. Warkentien was an important front office official the last couple of seasons when the team had a strong working relationship with CAA, the talent agency that represents Carmelo Anthony, J.R. Smith and Andrea Bargnani, among others. Warkentien was the Knicks' liaison with CAA, which also had special entrée with Dolan. But with Jackson's hiring, CAA is being viewed as just another talent stable. "The days of the Knicks catering to CAA are over," said one source. "Phil's not standing for that stuff." ... It's no joke — the Bulls really are expecting Derrick Rose to make it back from his latest knee injury in time for the playoffs. … Nobody is talking about the job that first-year head coach Dave Joerger is doing with Memphis, which has had an even better run than Brooklyn since back around the start of 2014. The Grizzlies, who were 30-13 in their last 43 entering Saturday night's game against Indiana, will be a team that everyone wants to avoid out West. Even if they're no better than the No. 7 seed. … Regarding Indiana's post-All-Star break mediocrity: We'll chalk some of it up to the fact they weren't a great team to being with, even if they did go 39-10 in their first 49 games. More recently, Paul George is learning how to be a superstar. His recent subpar play tells you that it can be a struggle, especially if there are off-court issues involved. The Pacers are saying, privately, that George is going through the same maturity issues all young players go through and they'll work themselves out.
