Thanks for your help.
1. I wouldn't. Cueto should be back soon, there's always a chance he's not what he was but I don't expect that. A 100% Cueto is worth more than Bamgarner. As the guy above me said Ryu and Iwakuma are both coin flips. I personally like Ryu more but it's not like I'd value him significantly over Iwakuma.
2. I like this trade for you. Choo is on a tear and you have the OF depth to sell him high, even if he stays hot all year (not likely) you're OF will be fine with Ethier (even better if you start only 3/4 OF but fine if you do all 5). Price is an obvious stud and I like him over Latos. For me the difference at the end of year between Price and Latos is more than Choo and Ethier.
