Lebron leaves Cleveland -- nightmare ensues
Pau leaves Memphis -- takes years and years for the team to recover while Pau hoists multiple championship trophies
Dwight leaves Orlando -- returns aren't in yet, but do you seriously expect them to be anywhere besides the basement?
Bosh leaves Toronto -- T Dot's long basketball nightmare continues unabated

I guess you could say Derron is another case where it evened out on both sides, but I kinda forget the particulars of what went on with Utah except they're stuck in the NBA middle class which many pundits now say is the worst place possible. NJ is a trainwreck but I think that's unrelated to Derron (and we'll have a more clear picture this year in Brooklyn)

so yeah, it's not the WORST TRADE EVER! but compared to what other teams got in return for an A-List departure, Denver did very well for themselves.
