Rajon Rondo is up to his old tricks. And when I say old tricks, I mean his typical, almost teenage-like borish behavior. Rondo was called for a flagrant foul in Boston's game against Miami last night. That would have been a foul in the NFL.Video after the jump.I'm a Boston fan, have been since I was a kid. I even like Rondo. He's the closest thing to a true point guard in the NBA. However, his act is starting to wear thin. When rumors were swirling in the offseason that Boston was considering trading him, I thought they were crazy to even entertain the idea. Now, not so much.Rondo got beat by Wade on the play, easily. And Rondo's reaction is just to reach out and deliberately grab him around the neck? I'd expect to see that from some playground thug who doesn't want to be showed up. But Rondo, this is the NBA, show some class. Grow up.
