How is this Clip-Atl trade?

it sounds good, but i would not give up horford for camby because they hawks want horford to be their "franchise" player for years to come. the east does not have much big men, even with the trades this off season, so keeping horford would be best. also, he is young and camby is old too. the rest would be to outweigh cap space with speedy and zaza for hart.
