We'll see how worried we are in June, when this board is going off about our lack of power, and that we did nothing to fix it. (assuming we stand pat)
You can throw all the steamer, projections, and predicted stats out there that you want, but we'll feel what it's like to have no power once the season starts, and THAT is when we will be worried. Problem is, at that point, it's too late.
Hell, even last year, when we had Adames and Yelich hitting, it felt like our line-up just didn't have the power needed to get us on that next level.
