I totally disagree. I've probably seen more of DC than anybody here over his career (watched most of his games as a hornet, some with the pacers and clippers) and he's been terribly inconsistent over the course of a season and never really established himself as a quality starter. He's very fast, and his quickness is an asset, and he's had stretches of good games, but he's not great at setting up guys or a consistent scoring threat. He's better defensively than IT, but when a team like this has no bench scoring and relies totally on two or three guys to make plays, then playmakers become more valuable, and IT makes plays.
I'd rather have Greivis than Sessions. I know I've been harping on Sessions, but it merits addressing, especially after Ray's rookie campaign. I honestly thought in the offseason Ray would be starting, and the fact that he can barely get minutes behind both a career backup in DC and a d-league PG in Sessions (seriously, he's at the bottom of the league at his position), keeps me scratching my head.
