> it’s a foul only if there is excessive force or done with the sole intent of blocking the keeper.

This is not how I’ve seen it interpreted personally. For instance, a player colliding with a keeper when attempting to win a header is frequently called as a foul when they’re not attempting to block the keeper or using excessive force.

Side note: I would also argue the UCLA player probably is attempting to obstruct the keeper.

Either way, probably not worth arguing over it. Just how I’ve generally seen it interpreted. Respect that you’ve seen it differently.
