Great trade for the Mariners. Morales was destined to be a star before he broke his leg in a freak accident. Even if he is just the Kendrys of last year it is a nice addition for Vargus who is a nice pitcher, but the Mariners have enough pitching to find another 3-4 starter. Tons of upside here and they still have all their assets for another bat.
I like this trade even more for Seattle since Vargas was very much a creation of Safeco Field (his home/away splits were terribly slanted) and his effectiveness might dim now that the Mariners are bringing the fences in a bit.
"It breaks your heart. It is designed to break your heart. The game begins in the spring, when everything else begins again, and it blossoms in the summer, filling the afternoons and evenings, and then as soon as the chill rains come, it stops and leaves you to face the fall alone." --- Bart Giamatti, on baseball
Fielder isn't declining at all. It's very fair to presume he WILL start to decline in a few years given his body type and the fact that he'll pass 30, but I'd say Fielder will still be a superstar through at least 2015.
