Big-time deal that gives Atlanta both of the Upton brothers without sacrificing 'much' of their prospect depth, though Delgado was arguably their top minor leaguer. Arizona gets a very good player in Prado that fills their hole at third base.
"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
I haven't seen anything special out of Delgado so I'm not too concerned about the longterm ramifications of this one. Especially getting Justin Upton at such a young age. This definitely makes up for the BJ Upton signing; who I deemed to be a more expensive version, and less impactful player than Michael Bourn.
You don't have to declare it illegal. Simply say "Join you're little union if you want. But you can't play with us if you do. Go form another league if you don't like it." I guess you mean that they favor it like Sammy Sosa does?
