Today’s Celtics-Heat game is being marketed as Ray Allen’s grand return to Boston, although plenty of C’s fans probably won’t be too excited to see him after the guard left their favorite squad and signed with the reigning champs down south. Well according to the Daily News, one of Allen’s gripes about his time in Boston was that he was fourth in Coach Doc Rivers’ pecking order, behind Kevin Garnett, Paul Pierce and Rajon Rondo: “The Celtics have given video tributes to the likes of Eddie House and Big Baby Davis when they returned with their new teams, so of course they will honor Ray Allen on Sunday when he comes back to TD Garden for the first time as a member of the Miami Heat. There will be a lot of smiling through gritted teeth on both sides. The Celtics were not happy that Allen defected to the rival Heat last summer as a free agent, while by the end of his time in Boston, Allen told close allies that he felt he ran fourth on Doc Rivers’ list of favorites, after Paul Pierce, Kevin Garnett and Rajon Rondo.”
