San Francisco Giants organization discussion

I am now working on the New York Yankees top 20 prospects list. The next team in line is the San Francisco Giants, to be followed by the Los Angeles Angels, Philadelphia Phillies, Texas Rangers, Cincinnati Reds, Baltimore Orioles,and the Arizona Diamondbacks.

Use this thread to discuss the San Francisco Giants organization. Possible points for discussion include, but are certainly not limited to,

***True or False: 2015 was the best year of Matt Duffy's major league career. Why or why not?

***True or False: 2015 was the best year of Chris Heston's major league career. Why or why not?

***Do you see any Duffy or Heston-like rookie surprises on the horizon for the Giants in 2016?

***Your take on Phil Bickford, 2015 first round pick? He was lights-out in rookie ball (2.01, 32/6 K/BB in 22 innings, just 13 hits) but he was also a college guy going up against high-schoolers. Does he start or relieve long-term?

***This organization has won three World Series titles in the last six years. But hey, nobody is perfect. If you could nitpick something about how the system develops players, what would it be?

***As always, feel free to discuss sleepers,overlooked prospects, etc.
