You have to look at it in more than a one-year time frame. I understand that keeping Hader in the pen might be better for the 2018 Milwaukee Brewers. However, if he is put in the rotation, throws around 150 innings, and continues to develop he will be far more valuable over his time as a Brewer as a starter than as a reliever. Yes. It would be very shortsighted of the Brewers to use Hader in the pen in 2018 only because he makes them better next year when they could have a young, controllable stud, atop their rotation for the next few years if they put him in the rotation. I know I've repeated myself but to not test the waters with this guy is a huge, huge mistake on their part if it does happen. It's totally possible that Brewer scouts just don't see Hader as a future ace for whatever reason, pitch mix, control, etc. Many scouts feel that way about him. Honestly, I get where you guys are coming from and I definitely agree with some of it. If they see Hader as a pen arm and lose out on an ace because of it if they're wrong, that's a franchise changing mistake. So even if there are some growing pains in 2018 it may be worth finding out. I am a bit concerned of the void that is left in the pen by his departure. I think the value he brought to the pen last year is understated. I like Williams and Houser, but what I'm really looking for is that power lefty, and Wang and Suter obviously aren't it. He's not ready yet but I'd love to see Kodi Medeiros eventually fill that role. Like Hader, he's got an electric arm but in Kodi's case I do think any future value is in the pen. I'd like to see him start 2018 in Biloxi's pen, leave him alone and let him develop as a reliever and see what happens.
