I have a question about the usage of the verb "prove". Suppose the context is a store:
Dictionaries say that the "prove somebody to be [adjective]" pattern is standard English, but are silent about the "prove somebody to [verb phrase]" pattern (like "proved him to have great courage" and "proved him to have great intelligence").1. The latest sales figures proved the manager to be competent.
2. The latest sales figures proved the manager to have leadership.
So, is sentence 2 wrong?
It's not colloquial.
