ESPN – The Miami Heat have scored another free-agent coup, convincing Ray Allen to leave a richer offer from the Boston Celtics and agree to sign with the defending champions, agent Jim Tanner told ESPN.com. It is believed Allen will accept the Heat’s mid-level exception that starts at $3.09 million and could be worth a maximum of $9.5 million over three seasons. “

#HeatNation please welcome our newest teammate Ray Allen #Wow #JesusShuttlesworth,” LeBron James tweeted Friday night.

Boston, where Allen had played for the past five seasons and won a championship in 2008, had offered Allen a two-year deal at double the salary for $12 million plus a no-trade clause.

Heat owner Micky Arison celebrated the news by tweeting,”Its 2:30am in London and I was just woken up with great news. Welcome to the family #20.”

According to multiple league sources, Allen had become frustrated during last season when the Celtics offered him up in trade talks and then stripped him of his starting job in favor of the younger Avery Bradley. Allen, who averaged 11.9 points and shot 35 percent on 3-pointers in the Eastern Conference finals loss to the Heat, also had a deteriorating relationship with point guard Rajon Rondo. The Heat’s offer to Allen centered on playing with James, Dwyane Wade and Chris Bosh in a variety of lineups. “HeatNation continues to grow,” Wade wrote on Twitter late Friday night.

I just got back from Nantucket and I got this shitstorm to deal with. Ray “Benedict” Allen going to the Heat. Now unlike a lot of Celtics fans I’m not totally mortified by this decision. Maybe because the rumors had been floating around for weeks. Or maybe because the only time I even started caring about resigning him was when the Heat entered the conversation. Before that I honestly didn’t give a shit. It’s like being totally at peace breaking up with your long time girlfriend only to see her start dating your biggest rival and then you freak out.   Like really?  That’s how you’re going to do me after all these years?  Just kick me right in the nuts?  I thought we’d always be friends.  I guess not. That’s pretty much what happened here.

So now the question becomes whether Ray deserves to get booed when he comes back to Boston? For me the answer is absolutely 100% yes. Total no brainer. He plays for the most hated franchise in sports right now. He accepted less money to go to Miami. He is willing to come off the bench for the Heat but not for us. He took the easy way out to try and win a cheap title. All that loyalty he earned with Celtics fans is gone. I’m no longer going to pretend that his 0-38483 shooting performance in Game 7 of the NBA finals vs. the Lakers didn’t cost us a title. I won’t pretend that he didn’t disappear time and time again in big playoff games. That he is brutally inconsistent. That he was slow as molasses on defense.

The bottomline is Ray Allen lost his job to Avery Bradley because Avery Bradley was a much better player at this point in their careers. So I understand that maybe it was time for Ray to move on, but not this way. Not by spitting in the face of Celtics fans everywhere and signing with the Heat. Like I said automatic boo. Automatic. I just hope Momma Allen has fun in her bedazzled Heat shirt wiping Gloria James asshole whenever she shits because that’s what her new life is going to be like. And when Ray’s career is over and he’s done playing with Miami I won’t hate him. I won’t boo him. I’ll just have apathy.
