Honestly, the way that Rondo has been playing, and the way he can just explode and sneak his way to the basket for a nice lay up at times is a very crucial aspect of this team's offense.
It really p---es teams off when they are trying to focus on stopping Boston from scoring in other ways, only to have Rondo take it right inside for a sneaky one. That's an aspect of his game that will absolutely be missed if he can't play.
