Setting up Rashford is a serious bonus, which can't be overlooked. We have a lethal 30 goal-a-season, wide forward. If we have a striker who can't work well with him it's pointless. Ronaldo scored a lot for us in 2021-22, he scored 24 goals with 18 coming in the league. But the fact he sucked up all of Rashford's output meant we were still very poor in attack. We lost Ronaldo and yet we scored more EPL goals (58) compared to the season before (57).
On the bolded, pass completion rate for a striker doesn't mean anything at all. Pointless stat, especially if it's not translating to assists or goal creating actions. RKM simply tries more through balls, which leads to more assists yet lower passing %. None of them is in the team to be a metronome, to recycle the ball. They are strikers, they are there to make things happen. RKM has more assists, more progressive passes, more goal-creating live passes and more shot-creating live passes per 90 than Hojlund. By a 3-to-1 ration no less. He is undisputedly the better passer in every way that matters for a forward.
Also, Hojlund simply doesn't score more per 90. Not in any balanced view. If you take the league alone, or the league and domestic cups then RKM has better return than Hojlund (0.6 vs 0.48 goal per 90). That is the like-for like comparison. RKM's stats are skewed downward by UCL participation. Which is objectively a much harder competition for clubs of Atalanta's or Frankfurt's stature. Atalanta didn't even reach the UCL groups they got knocked out in the qualifiers by Dynamo Kyiv. You can't compare apples with oranges.
It isn't far better. The npXG in the league is 0.40 per 90 for RKM and 0.47 for Hojlund. But yes it is better and it does fit with the eye test of a striker who's got better with in-the-box movement and positioning. I agree.
But when it doesn't translate to more goals for himself or his team-mates, it's the less important stat. RKM scores and assists more per 90. And an all rounder is a better than someone who is only good at 1 thing. If Hojlund goes through a difficult goal scoring patch, he doesn't bring anywhere near as much on the table as RKM. His defensive actions all lower, his dribbling is worse, his passing is worse, his first touch and back-to-goal play is worse.
