Trade one is hit or miss. I think Greinke is overrated. His splits are usually insanely strong, meaning he only really has good numbers at home. How much value does a really half time starter hold to you? BUT Cole is a good prospect, so you'd potentially be taking a pitching hit long term. Tulo would be a huge upgrade at short, you'd get a decent starter and a good closer to boot. I don't see it as terrible, and would consider doing it if your minor league pitching depth is strong.
Trade two might be better though. You'd be straight up trading for a big bat, so things wouldn't shake up as much. The issue is that your SS problem wouldn't be resolved at all. Think you could then trade Morneau for an SS?
