It's easy for a team to love Ray Allen at $3m per season. A gimpy Ray Allen, on an expiring $10m contract, with festering personal issues between him and the team's QB, is an obvious choice to be trade bait.
Danny Ainge should have shipped Allen's ungrateful ass out of town when he had the chance. Remember,t his is a guy who played for only two plus-42 win teams in his 11 years before Ainge rescued him from Seattle to be a third fiddle in Boston.
Ray Allen should be comfortable with his role as 4th banana in Miami, since that's what he's been here in Boston. On the court, he's sub-par in all facets of the game besides shooting threes, and he was unable to cope with his declining abilities.
He took the easy way and signed with Miami. Instead of having his number retired with the most storied franchise in basketball, he chose to become a bit player in Miami. Don't let the door hit you on the way out of town, you petty ingrate.
