This summer I'm planning on buying 2 more, not sure which ones it's going to be yet but I liked the all-star jerseys of this year, they looked pretty unique so I'm thinking of buying an eastern All-star jersey of Paul Pierce (I prefer the blue/white one over the red/white ones of the west else I'd take Roy)
And probably a Red Trailblazer jersey, not sure which player... depends on this offseason, but it might be Oden or Fernandez (don't know which number he will play with).
