Yeah, I was surprised they gave up Lawrie for Marcum. Talk about a panic move ... Marcum is solid, but I don't think he had that type of value.
Lawrie was the type of position player that could've been a key to landing Greinke.
Id rather go all in on the ace like Greinke, than trade an upper echelon prospect for a solid 2/3. I know the prospect may not amount to anything, but we know the value they possess in trades.
