I love Oblak, but he's not better than Courtois IMO and nor MATS. The 2 week tournament is just an example. Courtois is rarely seen outside the top 5 throughout his career (with Atletico as well mind you).
Godin is better than Ramos and Pique? To people who have zero understanding of defense maybe. To people who know that CB look better when they're sheltered by 7 players in front of them, NO.
So to sum up your point about their lineups being equal (or better !) :
Goalies? Well Oblak's good, around Courtois' level. Let's forget MATS. Doesn't fit the point.
Dmen? Let's not look at the system and let's say Godin is the second coming of God. OK.
Midfield? Well let's ignore and pretend Saul/Koke are better than Modric and Busquets (or Rakitic, Iniesta, Xavi etc...).
Offense? Well let's ignore as well because... well, there ain't much to say.
So all you could come up with is that Oblak is around Courtois' level (ignoring MATS) and that Godin is somewhat individually better than Ramos and Pique (while in fact he's even worse than Varane and Umtiti).
Who's grasping at straws?
