He left to pursue a better opportunity.
Let's go through this again.
1. If Ray had left for a team paying him more money, no one would have been thrilled with it but I think the majority of Celtics fans would understand.
2. If Ray had left for a team where he was going to play a larger role than in Boston, no one would have been thrilled with it but I think the vast majority of Celtics fans would understand.
3. Ray actually left for less money to go to a team where there's not only less of a role for him than in Boston but a team that has beaten Boston the last two seasons and remains its biggest obstacle to winning another title.
4. Let me repeat that. Boston was willing to pay Ray MORE money and unless you think Doc was going to completely change his coaching style in Boston, Ray was still going to play ALL the time. Even with Avery Bradley last year, Ray averaged 34 minutes a game during the regular season. Does that sound like a guy who has to worry about being "eased out" of the rotation? Compare that to playing in Miami behind Wade at the 2, Chalmers at point and with Miller, Battier, Lewis and Jones all competing with Ray for the same role on the team.
Given those 4 things, Celtics fans are totally, utterly and entirely entitled to be ticked off at Ray. Yes, no one should be wishing an injury on him. However, this serf-like attitude that we're all just supposed to tug our forelocks and say "Good day, milord" at Ray's actions is ridiculous.
