He was talking about someone whom I knew well, but had not connected with in several years—Johan Ruijsink, the non-playing captain and coach of Europe’s Mosconi Cup team. What is there about a man who can bring together players from four different countries, with four different languages to form a cohesive battle unit that laid waste to the best of American players?
... but in his two years as coach, Marcus Chamat has been even more successful than Johann, winning by a combined score of 22-10. Niels of Netherlands/Denmark, Darren and Mark from England, Jayson from Scotland, and Albin from Austria, also represented four different countries.
Coaching a team that has far superior talent is a challenge but a far less challenge than coaching a heavy underdog, which Team USA is year after year. To be fair, Marcus has not had teams as strong as some of Johann's. For example, the 2013 Team Europe had four World 9-ball champions on it and its fifth member had collected a bronze in the World 9-ball championships.
Ralf Souquet was coached by Johann but never by Marcus.
The evidence suggests that anyone who coaches Team Europe will look like a genius right now. It's chiefly about the players.
