Totally agree on your analysis of Muyl in RB system. Doubt he'd be as effective in our system where the emphasis is (supposed to be) on possession and letting the wings create 1v1.Setting aside the silliness of whether he is better than Jack, I think Muyl is pretty important to what the Red Bulls do. Huge work rate and a key cog in the press and defensive structure. He isn't going to be a big goal scorer or creator, so maybe he is a case of a guy who is the perfect system for his skills, which, in fairness, might make him less of a prospect in a vacuum. But, in terms of in-season contributions, I think he's in the top 10-15 or so.
All that being said, I may be overrating him since I see the RB a lot more than some of the other teams in the league.
In many ways I see Muyl as a less technical version of Fagundez - although better defensively.
