He has a couple of special qualities which makes him incredibly dangerous winger when on form. He is not a midfielder like Park or Fletcher, he is a winger that provides serious amount of pace. His end product is bad, but for such a young player he isn't a bad footballer either just because he isn't good enough to start for Man Utd. I think he might prove a very useful signing like Park, however in a completely different position, with a different skillset and with a different type of impact. I still think he'll prove useful due to his qualities not because of some made up thing that portrays it like everyone wants to have a team full of Rooneys, Welbeck or Fletchers. Literally nobody is saying that, I don't know why so many people keep saying it like it's a thing.
Running fast without the ball is not a special quality.
Forget comparing specific attributes, your squad players should first and foremost be intelligent and technically strong footballers unless we're suddenly turned into Burnley over night and putting a shift in is the real deal now
I think he's been dreadful now for quite a while, and needs to step up if he wants to remain at this football club. All of this "it's his his first year in the top flight.." business isn't the club's business. We need quality rather than sympathy. Maybe he finds that extra gear which has been lacking due to a lack of confidence but I'm not optimistic. It seems having elite pace has become some sort of saving grace offered to James which gives people a strange kind of hope that you'd never give the likes of Lingard and Periera. I mean, if he was able to ever look rapid on the ball, I could still understand. But he's brittle as feck and frightens no defender at all. So, yeah, he needs to show a lot more - dribbling, intelligence, passing, and just all round quality.
Also why on earth have you lumped Rooney Fletcher and Welbeck together?
