Impact of Sam Cassell

Cassell's knack is hitting big shot. Celtics will need him when they struggle, especially in the final minutes of a close game. His size provides better match-up against bigger, more physical guards like Chauncey Billups. While he may be slow to guard quicker guards, the front line could protect him. With his relationship with Garnett back in Minnesota and with Ray Allen back in Milwaukee, he should fit-in quite nicely.

Bill Simmons thinks that Cassell is unique. "Sam casting his shadow over everyone and everything. There's nobody in the league quite like him. He knows everyone on every team, every referee, every coach ... He's constantly working the crowd, the officials, even other players. He's always up to something ... Sometimes he dribbles upcourt, notices a defender innocently running back to the other end, then lurches into the guy and flops to the floor (always drawing a foul)."

There is, however, some reservation. "Cassell's arrival could ruin Rajon Rondo's confidence, which is in the process of being battered by Doc Rivers' penchant for yanking his minutes around." It will be interesting to see how Rondo handles it.

The best-case scenario would be the Rondo-Cassell tandem working like Tony Parker and Speedy Claxton of the 2003 Spurs. Remember the '03 Spurs -- 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. Claxton's ability to right the ship during Parker's off-nights plays a significant role in winning the championship.
