Scott Boras is believed to be seeking an eight-year deal for Holliday, a length of contract some interested teams like Boston are reluctant to match. A source familiar with the talks said the Cardinals have not been resistant to a contract that could reach eight years. "This is not about someone saying a lot of money has anything to do with value, not when the marketplace has already provided a way to determine that," Boras said. "This is a market of comparable players. There are known contracts, known comparables, and it's the market that defines the value of a player."
