A Loss at Home to Philly - By Design?

The Celtics let the 76er's back in the game in the 4th quarter, where they yielded a 11 point lead with 8:19 left in the game to Iguodala and Company, ultimately losing 95-90. It was similar to the game they lost on Saturday to the Hornets where they let an 8-point lead evaporate in a 4th quarter let-down. Now there appear to be some patterns in each where a lead is garnered in the 3rd quarter, and a meltdown occurs in the blink of an eye. I'm not pointing fingers, but the common denominator during both lead changes was Sam Cassell being on the floor - so that certainly brings into question what Sam Cassell is bringing to the Celtics versus a traditional House substitute for Rondo.
