Sometimes talent alone does not equal team success. Angelino is fun, he's exciting and he's new. These things will always cloud judgment.
And while I do think stats can be interrupted however you want them to be, there might be something to this. Watch how many times he got wrong-sided on Saturday night after he came in. Those are the nuances of the position that he is still struggling with. It's not about effort, or speed, or passing, it's about knowing where your mark is and. Not letting them get position.
All that being said there are extenuating circumstances with him. New league, new country, new to the pro game (playing other academy teams is not even close), a new team around him that is also learning, a new RB, etc.
I feel the reality falls somewhere in the middle, he's not great, though he could be, he's not the reason goals are given up either. It's all shades of grey.
