Because Hammel is pitching his brains out like he never has, doesn't mean buying on that high is a good idea. I'd rather have a cheap 25 year old in Nolin pitching for us now (when healthy) and going forward opposed to paying with a prospect and paying a salary to get a junky pitcher.
A slightly worse Nolin for LG Min, is far better than Hammel at whatever he makes, even if it's LG Min.
