tyronn lue is much better than cassell, he's younger, actually plays pretty above average defense, and isn't too much of a downgrade from eddie house on the shooting end.
people think lue and they think suck mainly because he's been on s***** teams his whole career (spare me the two laker championships he had, he played 40 games those two years). he played on two mediocre wizards teams, then on a pathetic magic, an overachieving houston team, a bad atlanta team, and behind jason kidd on an overrated mavericks team. he might be way past his prime from when he had 13/5 one year, but he still soots really good percentages, plays very smart and heady basketball, makes plays, and plays defense.
i think lue would be terrific coming off of the bench for 10-15 minutes a game to spell rondo
