The first deal shouldn't be anything but a fast no. Sure, Hamels has his injury worries, but your SP can accommodate him, and in a 10 teamer (Standard for ESPN, no?), you'll find SPs when you need them.
The second deal is better, but I couldn't find two droppers. Even F. Codero might rebound, and you'd be left paying for saves in that deal. Ibanez and Derosa are nice players, but in a 10 teamer, I'd not trade for them. You could always drom Cordero for someone if he is hurt or losing it, and you've got so much hitting that Dye's a good risk for you.
No to both. The first is esentially Pujols for Braun since the pitchers are equal, and I'd rather have the greater talent and the infielder.
I'd encourage everyone to trade Dice-K, because he should be expected to perform more like '07, but try for one quality player in return, whether it is a pitcher or hitter.
