Portland needs a SF and if they don't land a top 3 pick they'll probably look at trading it. Other players of value that could be available are Jarrett Jack, Martell Webster and of course Zach Randolph. The Blazers like Jack and Webster a lot but they aren't viewed as critical players to the teams future core of Roy and Aldridge.
Granger seems like someone the Blazers would have a lot of interest in. How much value does Granger have to Indy? What would it take to get him to Portland?
