Up until a few weeks before this 1977 appearance on The Match Game, awesomely-jacketed Brian Billick "was playing professional football." The coaches didn't think he was "quite the caliber" that a professional football player should be, though, which is why he still haunts us from the broadcast booth.
Billick lost, but he still walked away the Match Game home version, which was nice.
