This guy gave all he had to the Celtics and now Danny is just casting him aside. He said he can't use a valuable roster spot for him. He didn't seem to be concerned about using a roster spot for Sam Cassell, who never played a minute for the team. And we used a roster spot for Patrick O'Bryant, who might as well have been injured for all he contributed. And then there is Tony Allen, who has been kept on the roster even though he has been injured much of his career and didn't add much when he wasn't. Leon deserves better than what he is getting from the Celtics. Add your name to the petition to let Danny know how Celtics fans feel about it.
