Well, we knew he was going somewhere, just not where.
I feel like the Angels have been the one team that swoops in at the last second and gets the biggest stars to add to the already expanding roster. That rotation is awesome enough, with Weaver, Haren, Santana and Wilson, but now the fifth man is thrown into the hat, and the rotation turns into the AL's answer to the Phillie Four.
This kinda gives a bit more power to the AL, but everyone's already been saying it's off balance, so who cares.
In exchange, the Brewers received Jean Segura, the Angels' top position player prospect. This could do them some good in the future, and who knows if head-case Greinke will stay full focused in LA.
Amazing stuff, and the deadline hasn't even hit yet.
