The FA market for first basemen this year is very deep. In addition to Hart, there's Loney, Morneau, Napoli, Reynolds, and my personal favorite, Mike Morse who's been amazing at Miller Park: .432/.475/.973 in an albeit small sample of 40 PA. None of these guys are break the bank guys, but for the most part, they provide much more quality than what the Brewers have suffered with this year, and are better bets in the short term than what the Brewers have going into next year.
