Saibari out is definitely a blow but saying they have incredible depth without him feels a bit generous, Diaz is creative no doubt but he's never really owned a game at this level. France's midfeild will just swallow that creativity if Morocco can't control the tempo early on.
Belichick is the obvious pick but I always thought Bill Walsh changed the actual DNA of the sport more than anyone. Thoe west coast concepts are still everywhere decades later
honestly i dont see spain being that solid when they face a real counter attack. they look pretty but that high line is a disaster waiting to happen against france or argentina
