The one caveat I would add, and I would consider myself neutral on the subject of currently NEEDING to add more power now, is that there are really two seasons to deal with. As you mentioned, the Brewers seem to have the regular seasons nailed. Right now I think the focus is on building the best 40 man roster that can survive 162 games and come out alive at the end. I think the 2nd roster that needs to be built is the playoff roster and that is where we maybe need to be more aggressive, maybe more so than we have in the past. Once we hit summer and are positioned nicely ... I think "Do we have enough power?" is a super appropriate question to ask and act on. Right now, I really want the best players we can get that can get us the 162.
Who could have known Tobias and Perkins were going to be season savers when it all started last year. Imagine if he had "dealt from depth" before the year and traded Perkins for someone with power? Who knows, in a weird twist of fate maybe Mike Boeve ends up hitting 12 home runs for us this year.
Again, I don't think anyone is wrong in this instance ... but personally I just want the best players on the 40 man that we can acquire to start the year, all else equal. Sorry I rambled, hope that makes sense.
