Not sure why the Brewers have to trade an OF. While it is smart to trade from your strengths, this year should have showed us all why you cannot have too much depth. Weimer, Perkins, and Tapia basically gave us ABs of a full time OF at relatively poor production. Injuries to Taylor, Mitchell, and Frelick quickly depleted the depth we had.
Yelich would need to move from LF, but I could easily see a Mitchell, Chourio, Frelick OF on opening day. Yelly will need to move soon anyways, so I wont be shocked seeing him in 1B/DH/LF next year. That leaves Taylor as a backup OF and Weimer/Perkins as depth in AAA. If the Brewers are considering this, we will start to hear some rumblings about Yelich buying a new 1B glove in the coming months.
