I have to admit that sometimes it concerns me to see Rondo with gigantic ice packs strapped to his knees at the end of a game where he's played 35+ minutes.
We all know that Rondo is durable and has tons of stamina, however he is still a human and has his limitations. The mere fact that Rondo has trouble converting some of his free throws can make him a target for being fouled needlessly, which could tire him out by the time the playoffs start.
Interesting to note the fact that Rajon Rondo barely lost to Kevin Durant in the NBA horse contest last-season. Also, the Celtics and the Thunder finished last year's regular season with identical records; however the Thunder lost in the first round and the Celtics barely lost in the finals. I'm hoping that guys like Robinson, West, Von Wafer and Avery Bradley can step in for Rondo just to keep his legs fresh so he is feeling less strain once the playoffs start.
