Darth, I give your ratings an F. Simply because you don't seem to recognize that there is no gain without risk.
Setoguchi was a low-cost gamble. The signing and subsequent handling was done perfectly. He was given a chance to succeed, didn't and was gone. If he had've been signed for more, or for a longer term, then I could agree with a poor rating.
Ortio for 2y is also a smart signing. A longer term would necessitate more money, since Ortio and everyone has reason to believe he will be worth more money 2 years from now. But if Ortio didn't work out, then you'd be stuck with a non-performing asset at a high cost.
Don't quit your day job. You'd make a terrible GM.
