Maybe in the sense that you have to think of different phrasings to sound natural while rhyming. You could argue that you're expanding your ability to construct certain thoughts so they rhyme while still sounding like normal speech. So maybe a little boost to wording in general when not rhyming. That's the only connection, I think. The whole purpose of rhyming is to show how well you can write with a restriction so it doesn't cross over much.
