If we're going after RFA tho one to keep an eye on is N.Batum. I doubt Portland lets him leave but he's got great length and really started coming into his own last year. Another 6'10 23 yr old and he can shoot the three and defend. He could also potentially fit in very nicely with the foreign players we've began to assembly (Nene, Vessly, fellow countryman Seraphin)
Would fill a huge void at the 3 and would make Beal a great choice.
