Portland has dramatically improved their team this summer: Aldridge, Roy, LaFrentz, Magliore, keeping Pryzbilla.
Raef is not an upgrade at all. he is nothing but a salary cap albatross. Joel is what he is and they simply kept him so thats not an upgrade. LO is raw and nowhere near ready for the NBA. (personally I dont think he will ever be anymore than a backup) Mags doesnt fit unless somebody else is getting moved.
Blake was thier best PG last year as well
I dont see them as improved at all.
