To me Hader's future trade value is tied to developing his slider (or breaking ball, as Augustine calls it) or something else off speed. You can only throw so many 4 seam fastballs at 92-95 that maintain the swing plane before they start to time them. While still outstanding, he became SLIGHTLY more hittable last season when he had nothing else to throw. That said, you make it known he is available, but the conversation starts with quality players not necessarily quantity. If nothing wets your beak then let the season play out. If the Brewers fail to contend, they can always see what the trade deadline market offers.
