It's time for some game theory. Every week, it seems like another Premier League team is hiring another set-piece coach. At this point, it's just malpractice not to have one. The most generous estimates suggest that they could be worth as many goals as an £80 million striker, adding something like an extra 0.75 goals per game to a team's full-season tally. But even the least generous estimate suggests they're worth it.
