I will take Murphy, Powe and Bibby.
Murphy for offense and rebounding, Powe for rebounding and low post points with Bibby for insurance at the point and allow Delonte to get back to the wing where he is most effective.
As to the reality aspect, Murphy and Bibby have to love the chance at a ship with this veteran crew and they would easily fit in. They also have made their money and see their career winding down. How comfortable would they be in South Beach with that crew? Powe is still our boy from way back and already has said he wants to be here. He is our family.
