In one of those interview clips with Papi, he said he wants to spend time being a tourist in his own country, while gorgeous beaches were shown in the background. Too early for sure, even though it's a small country. The rest of the world is big. I'm sure he'll get wanderlust for some of it.I would say Chili Davis' job is as safe as any hitting coach in baseball and there is no way Papi is going to be with the team every day the year after his retirement when he has specifically said he wants to spend time with the family and do some traveling.
About Varitek, I wonder if he might go through pitching coach on the way to bench coach or manager. Dave Duncan, ex catcher, was one if the best pitching coaches, no doubt.
