Afflalo stinks at this stage. There is a reason why he has been with four teams over the last three years.
As far as Allen, I'd take him on a one-year deal if we were able to land Hayward and George (and I'm not even sure we would have the cap room to do that at that point). Otherwise, I don't have much interest. I love the dude, but he is incredibly injury-prone and is 35 years old.
Signing Allen just for the sake of filling a spot wouldn't be very wise and would take playing time away from Brown and the rest of our young wings.
