I'm sorry, but there seems to be a mistake in your request. You've mentioned that Hal Pennington was active from 1937 through 1937, which suggests a career span of only one year. Additionally, there is no notable information available on a football player named Hal Pennington active during this period. It's possible that you may have confused the name or the timeframe. Please provide the correct details so I can give you an accurate summary.
