If this team is going to win next year, they are going to need a lot of things to trend in the right direction for them. Cain, Yelich, Garcia, Narvaez, and Hiura rebounding. Young guys improving, such as Urias, Lindblom, Houser, etc. And, of course, staying healthy. That all said, this team will never be a juggernaut. But if we win, it'll be with an adequate offense, good defense, and solid pitching - including a exceptional back end of the bullpen. That means Hader and Williams locking things down. Thus, unless you are blown away with an offer for Hader - you just hang on to him, and see how the season goes. If things don't go well, he'll still have a ton of value during the season. Yes, injury of diminishing effectiveness is always a risk. But so is trading him. May as well see how this team performs - and then make a move later if it's deemed prudent. Thus, just hang on to the guy unless you are blown away. SD or whomever will come calling in July if we become sellers - and the price will be just as high - if not more.
