*Ron Artest took to Twitter to come back at Celtics coach Doc Rivers’ recent comments about how Boston’s starting five never has lost to the Lakers’ starting five.

“Our starting five against the Lakers starting five has a ring,” Rivers said.

In other words, is Doc saying the Lakers’ 2010 championship doesn’t count? Well, Ron Ron isn’t about to let Doc go unchallenged:

RONARTESTCOM: Boston lost to lakers because of Kendrick Perkins injury. What about in 08 when Bynum was injured. What about this year Bynum was injured ..

RONARTESTCOM: What about Kobe played with a broke finger …. What about Ron artest defense When the Boston staff said Ron artest was too slow

RONARTESTCOM: Doc got one million excuses.. Just come back this season a take what you want…

RONARTESTCOM: The lakers with Bynum in the playoffs healthy has not lost The same way whoever whatever hasn’t Let’s not mention the stats on lock down

RONARTESTCOM: Nobody made excuses when Boston came to sac town when I was there and they embarrassed us. Acting like they were hardcore.

RONARTESTCOM: Let’s see if my defense is less effective this year. Come haters Count me out Super dis respectful

RONARTESTCOM: So Boston is going to championship right past Miami?

OK Doc, your response to that is …?
