Which was the best trade?

[*Nately120*]

Are we talking about the trade itself or the results of said trade? I mean, we can trade an old jock strap for six 1st round picks and they could all be busts, but it's still a pretty good trade, right? Or we could trade AJ Green for a 7th round pick who leads us to 5 Super Bowls which makes that a pretty lousy trade, but with great results, right?

Just what DOES a great trade make?
