If Josh Smith adds value to a team, why didn't Detroit improve at all after he went there? They were 29-53 they year before he got there, and had the exact same record in Smith's first season, in the weak eastern conference. They improved slightly the year before Smith got there-- and with a young Drummond and Monroe, doesn't it make sense that they'd get at least a tiny bit better with a new athletic defender? If anything, he was so bad that he negated the growth of Detroit's young players to put them back at 29 wins. That's why I think adding him only appears attractive, but is actually a case of subtraction instead of addition.
