You can say what you want about Jermaine Jones, but you should never question his commitment to winning.
Shortly after U.S. national team head coach Jurgen Klinsmann announced his 23-man roster for the Gold Cup, Jones posted a statement on Instagram that expressed his desire to be the best at both the international and club level. The post has since been deleted, but it still serves as a good example of Jones' drive.
Jones, of course, was a significant presence during the New England Revolution's push to the MLS Cup Final last year as the team only lost twice after he signed late in the summer. Jones hasn't been quite as influential this season as the team is 3-1-5 with their Designated Player on the field. That said, the Revs are 3-5-1 when Jones has been sidelined.
A fully healthy Jones playing in his preferred midfield spot is something to be feared in MLS. Furthermore, he's obviously unaffected by the duel sports hernia surgeries and his subsequent exclusion from the Gold Cup. The motivation is still there, something that Revs fans should be happy about.
