As far as having an Allstar on a rebuilding team, is there another type of player that would be better than Rondo to keep around?
I believe the contention that Rondo is better with better teammates makes him more valuable to a rebuilding team who is interested in collecting assets, as he will be limited in what he is able to do due to a poor team, resulting in a higher draft position. It additionally profiles assets, and makes them look better than they really are, and can help Danny get value for them in trades. Finally, his style of play may be attractive to other players in the league, as he will make their lives easier and allow them more opportunities to score due to his aversion (or inability) to do so himself, and/or his unselfishness (or selfish lust for the assist).
It seems a lot of focus is on 18 or bust, and to me, a player that turns a playoff team into a contender and maximizes the value of your other assets, is more desirable to keep around than an equal talent who will win you more games but not take you over the top.
