You choose to ignore several things.
No manager has ever called him out for laziness unless I forgot about something. No manager has benched him for similar reasons either. You really think Rashford has played under 5 different managers now and all of them subordinated themselves for him whilst he was ignoring their instructions? This idea gets even less realistic when you remember ETH has benched Rashford himself for being a few minutes late to a team meeting.
It's also very often a tactical instruction for your best and furthest upward player to conserve energy and don't drop deep, as funny as you might find this. When you win the ball back and can launch a quick transition or counter attack, do you want Rashford to be next his fullback, helping him near his own box, or do you want him near the halfway line to receive a ball from Bruno?
And before you tell me Rashford isn't good enough to be a "luxury" player, as I've got that type of answer to this before: it's tied to tactics, not the player's level. Just because Rashford isn't Messi or even Mbappé, that doesn't mean he isn't allowed to do something the manager probably asks from him anyway. And he's still one of the best wingers in the Premier League purely because of his pace, power, ball-carrying and ball striking as well. What I just described can be applied to any level as well, from the Premier League all the way down to Sunday league football.
