you have some good shooters. oladipo, fournier, frye, harris.... vucevic can drain mid range shots as can o'quinn and nicholson.
if i were you id run the offense through vucevic. pick and rolls, pick and pops, post ups.
id use harris like a mini melo. high post plays, iso's, some mid range and three plays mixed in.
oladipo would be my 3rd option. id mostly try to slash with him and find him for 3.
guys like gordon and harkless can be great in transition or slashing to the basket. can also make the occasional jumper.
fornier would be my 6th man. i love having a guy who can come in and shoot the lights out.
its not the best team to work with but they have some solid pieces.
