yea the shareef trade is worth it for sure, as for the other one, it really depends on, how much you need a SG/SF, and how much backup you have after Maglore is gone. I've used pierce before, but fore me, he's a little slow.
the good thing abou this trade is that I will have a good SG for this season. I also Like to play with N'Diaye. And at the end of the season I will have something like 25 mil. on capspace
