I did not realize how much of the Union’s offense ran through him

That’s true in games, too. Sullivan takes 10.3% of his team’s touches, the most of any teenage MLS winger in at least a decade. Second place is Alphonso Davies, now of Bayern Munich, the best homegrown player the league has ever produced.

I had no idea he was already linked to City. I don't follow up-and-coming players or youth potentials at all, so I hadn't heard of him until he started blowing up the last month. Crazy that we have a 16 year old in the US already signed to a PL club.
