There is insurance for injury. The scary part of a 10 year deal is trying to project when the skills will start to diminish. For some players guaranteed money means less incentive to bust your hump to be the best player you can be. The message from this contract is the front office just gave a huge vote of confidence in the work ethic of Riley. They are convinced this kind of security won't go to his head and make him complacent. They are convinced he is the kind of leader you want on this team for the next 10 years. That is a HUGE statement about his makeup.
you can’t deny how he went from having the worst contact rate in baseball to an elite offensive machine. The work he out in I’m sure was noticed by the FO and organization.
