Be forewarned, rather than just looking at the stats (which decisively favor receivers who've played in the more pass-heavy NFL of the 21st century), my primary analytic tools were my left and right eyeballs. Numbers aren't liars ... but neither are my eyes, which tell me Steve Largent was better than Tim Brown no matter what their respective stats would have you believe. Deep down, you know it, too. In other words, I've limited this list to those guys who had one simple but rare trait: They were unstoppable.
