If following baseball transactions has taught me anything, its that if the Brewers do acquire someone like Bumgarner, there will be posters and fans who think they got a steal, while others will view it as an overpay. If you want a refresher, go look at the Yelich trade thread. Whether it is a fair deal or not is always in the eye of the beholder. With the Yelich deal, many loved it, while others would make you believe that the Brewers' sold their first-born child for a Snickers bar. When the Brewers traded for Greinke, they gave up Cain, Escobar, Odorizzi and Jeffress, and got two years of Greinke, Betancourt and $2 million. Obviously that extra year of control brings huge value. I think Ray probably holds a similar value to what Cain did at the time. I think if it is just a trade for one year of Bumgarner, a fair return would be something like Ray and a lower-level pitcher like Lemons or Jarvis. If the deal could be expanded, though, the Giants have some other pieces that would be of value to the Brewers, including 2B Joe Panik, SS Brandon Crawford, INF Alen Hanson, and pen pieces like Will Smith, Tony Watson, Mark Melancon, Sam Dyson or Ty Blach.
