"You have to trade Bradley Beal," Smith said. "The reason why you have to trade Bradley Beal is he's three years younger (than Wall), he's got two years less left on his contract, and if you scour the league every executive will tell you he's the higher commodity because John Wall's game is predicated on athleticism and speed and conditioning. Usually, father time says that dissipates, which means you're going to lower in value."
