In 1946, Cleveland Rams moved to LA, signifying the start of NFL teams moving west.
Three questions here:
Is it okay if I use "bespeak" instead of "signify" in this sentence? I've looked them up in the dictionary to see if there's any difference in their meanings, but to no avail.
What I am trying to say here is that NFL teams started to move west after the year 1946 when a team from Ohio decided to move to the West coast. Based on the context provided, is it correct to say something like that?
I would like to know if there's a better way to express the meaning here, but I want to make it sound formal.
