Turkoglu will probably be back by fantasy playoff time. I have to imagine that will have some impact (maybe not a lot, we'll see) on Afflalo's value.
Kidd-Gilchrist is a risk due to your theoretical rookie falloff facing a long schedule. Whether or not that is a substantiated concern, I think depends upon the player.
In terms of fantasy playoff schedule though, don't MIN and NYK have good schedules there? (in terms of games played). I don't have a paid subscription to basketballmonster, so unsure of ease rankings during that time period. Can only see quantity of games played.
I'd probably stick with George Hill, but if I were to trade him for the two you mentioned, I'd go with Kidd-Gilchrist.
I'd keep hill especially since Granger will be out until February and from there on he will be rusty. Indy loves hill right now and he seems to be playing very well.
