In case you missed the huge picture of Cassell on the front page of ESPN, here's part of what Bill Simmons had to say about him possibly joining the Celtics and backing up Rajon Rondo:
The best-case scenario would be the Rondo-Cassell tandem working like Tony Parker and Speedy Claxton in the 2003 playoffs. Remember, the '03 Spurs were pretty flawed -- they had Duncan in his prime, Robinson at the end of his career, a not-quite-ready Manu Ginobili, a hit-or-miss second-year point guard (Parker) and a bunch of role players. If not for Claxton's ability to right the ship during Parker's off-nights, the Spurs wouldn't have won the title. (Don't forget, Parker was so up-and-down the Spurs pursued Jason Kidd right after the season.) Rondo's 2008 playoff experience will inevitably play out like Parker's did -- some good games, some stinkers -- and when he committed those two last-minute brain farts in Golden State last week, it was a grisly reminder that young point guards can self-destruct at any time, especially on the road in big moments. I like Rondo -- actually, I really like Rondo -- but you can't expect a 21-year-old point guard to play consistently well for two straight months in the playoffs. Over everything else, that's why the Celtics need Cassell and his gravity-defying testicles.
