PG and SF.
If we land a top 3 pick, I think we should trade Bargnani/something else if required for another top pick if it's available. If we're able to draft, say, Irving/Barnes or Irving/Williams it would be an absolute heist. Hell, if we got the #1 pick I'd take Irving and maybe even trade up to #5-6 and go for Kanter.
I don't think one will put us in a position to do anything. Two, however, is another story.
