Cavaliers owner Dan Gilbert has congratulated Dallas on winning its first NBA title, denying LeBron James the one he left Cleveland to get.

About 15 minutes after the Mavericks beat the Miami Heat in Game 6, Gilbert sent a message on his Twitter page to Mavericks owner Mark Cuban.

"Congrats to Mark C.& entire Mavs org.," Gilbert wrote. "Mavs NEVER stopped & now entire franchise gets rings. Old Lesson for all: There are NO SHORTCUTS. NONE."
