well in all honesty, you got traderaped on the first one. cousins and lawson are both 2nd round picks with a really high upside. they are both just breaking out of their early season slump, so IMO you could have gotten a whole lot more... although marcus thornton is a good asset, gortat's dismal performances of late have left him in the possibility of getting benched by Gentry.
the second trade is ok. millsap again, has much higher upside that hibbert in terms of points, steals, and possibly rebounds. hibbert will certainly get you blocks though.
