Throwin' it back to the 80s! Interesting pairings. The Djokovic move seemed to come out of nowhere. Federer's work with Edberg is seen as a potential precursor to hiring him as a coach. Some good points about Djokovic/Becker being a potential volatile relationship because both are Alpha personalities. Fed/Edberg seems like a good pairing too. Only a few weeks till the season reboots!
