I would love Randle. Wiggins and Parker are obviously my first choices, but Randle and Burke would finally give us some actual leadership on the team. And he's a pure 4, unlike Kanter and Favors who are both kinda tweeners FWIW.
Randle & Favors would form one of the most athletic front court in the NBA. Not the most imposing, but very athletic. My dream lineup is still this:
Favors
Kanter
Randle
Hayward
Burke
Plenty of length. Plenty of scoring and shooting. There's slashing. Burke can run pick and roll with any of the big 3 all day long. There's enough 3pt shooting too with Burke, Hayward and Randle.
