I would say the deal was fair-ish, but you sold really heavily on a-gone. He's batting well, but he is going to go on a tear soon, his power is too good to be so quiet. I like davis, he's developing quickly into a legit SP, but I'm also really high on pineda and haren(obviously), so that's good pitching wise.
I really, really dislike reynolds. Just that. Santa will get better, but he's no a-gon.
So If I were you I wouldn't have made the trade, but, I wouldn't say you got robbed.
