In the case of Rajon Rondo, you can't teach an old dog new tricks. Back in May, Willie Cauley-Stein changed his middle name to "Trill," but even though the alteration was done legally, you shouldn't expect to see Rondo calling him that anytime soon.

Instead, the Sacramento Kings point guard is giving Cauley-Stein the veteran treatment by simply referring to him as "Rook." 

Kobe Bryant and him really deserve to be on the same team.
