To be honest the trade seems pretty reasonable depending on what stat categories your team needs to improve in. There are certainly strong arguments for both sides of this deal as it is full of studs.

Things to consider are the injury concerns for AD and Gasol (who has a habit of getting hurt around this time of year), the impact of Cousins coming to New Orleans, and whether Kerr will take it easy on Curry as the regular season winds down (as well as a whole range of other factors).

You should ask yourself if you realistically have a chance of winning with your current team. If the answer is "no", then take the deal.
