To OP: if that were my team, I would probably take the trade. I think it makes him marginally better. But if he is sitting at 4-2 or better, I can see him not wanting to take on that risk. It's certainly not a no brainer like you're making it out to be.
After rethinking, you're probably right. I do admit that I was a bit defensive earlier in response to arguments that I don't think hold water (i.e. inconsistency, AP will play harder, etc). We all agree Rice is bad so far, and history says he's much better--seems like too much upside in this trade to pass up if I put myself in his shoes.
Other team is 4-2, but they just traded away Jordy Nelson to get Brees (others involved) before losing Julio for the season. The other owner wants to move Brees and keep AP, and I'd prefer the opposite.
Ultimately, he decided to trade Brees away for Torrey Smith and Alfred Morris...time will tell if that was better for him.
