Re: Do you do this trade?
Cueto is good, and should be very solid this season. However, he is not worth buying so high right now. Ryan Braun is a top 15 player and Rios is good, but not worth Braun, even with Cueto.
Rookie pitchers very rarely pitch dominate the whole season. Your pitching staff should be fine as long as Liriano (who I have in 3 leagues) comes back and pitches decent.
I'd pass right now.
Matta = Really good
