Would you do this trade?

I would make the trade. Weaver is definitely lights out right now. Realistically though, he will drop off a bit. He will still be really good though. Kershaw is a great starting pitcher too though. The slight dropoff going from Weaver to Kershaw will be made up in getting Rivera and Stanton. You might want to decline the trade and see if you can get a little more out of it. If the other guy turns that down, then just go back to the original offer. I think it's a very good trade for you.
