This is why a team with championship aspirations keep vets instead of young guys with potential high rewards. There still has to be some balance of each, but having someone like JJ who you can rely on for consistency is SO valuable. No one should be overly surprised, this is what Jones has been doing for 4 or 5 years now, in varying amounts. Having a player that the coach knows EXACTLY what he'll get when he inserts them is one less variable to juggle when trying to fill rotations for illness/injury/whatever.
