Good point. Plus (from mlbtraderumors.com):
The Tigers receive four players: starter Max Scherzer, relievers Daniel Schlereth and Phil Coke, and center fielder Austin Jackson. The Tigers get five years of Scherzer, six of Schlereth, five of Coke, and six of Jackson, potentially 22 years of control in total. Scherzer, 25, and Jackson, 23 in February, are probably considered the prizes of the haul.
That's a lot of years of cheap control for Detroit.
