Opinion: The sudden arrival of [SPOILER] has convinced me that the next Avengers movies need to go smaller, not bigger

The ingredients are there for Cap to form a version of the West Coast Avengers in the MCU, even though Sam Wilson in the comics was never a part of that team. Avengers: Doomsday could skip over his recruitment of the team and already have them in place.

Brave New World perfectly set up Sam Wilson to lead the new Avengers team, and he could choose these clear candidates for the roster.
