agreed about ausar. if some of the draft honks are right, you may be able to get the same player (or better) in Ausar 7 or 8 spots lower than amen. simply a better value. not sure there is a great argument amen is really even better than ausar at all, let alone several spots higher.
scoring is about even, assists are about even, rebounding advantage goes to ausar, three point shooting goes to ausar (ausar takes more and has a better percentage) and i think he's a better defender. amen has a significantly better FG%. in terms of size and athleticism they are clones. they are about as even as you can get - so if you can get one of them 8 spots lower, the value is just so much better.
