Kind of true
TACO does a lot of stuff outside of the game. Like tactics, smokes, demo analysis and such (Fallen said this in a vlog once but it's in Portuguese). And, according to Fallen, he's is essential in his role and he likes him because he is a versatile player, he can basically play any role and his main objective will always be the team first, and not the individual. He is an altruist player.
But yeah, no doubt that when it comes to raw aim and skill, Cold, Fer and Fallen are on level above TACO and Felps.
