Rondo says goodbye to Boston, hello to new teammates via Twitter

My time in Boston has meant so much. I've grown up with this city both as a basketball player and person. The love I have for the most loyal and supportive fans in the league is unmatched. My teammates have shown nothing but heart the last couple of seasons.  They are some of the hardest working guys I have played with and I wish them the best. I've experienced my most successful and challenging years with the Celtics, fans and city. The opportunity to play with guys like Dirk, Monta, Tyson and the young talent of Chandler is exciting.  I look forward to building something special in Dallas.
