I'm no Namath fan by any rights, but I'll do my best to set the record here:
1. When Whatthehellsgoingonouthere stated that Namath had one great prediction and one great game, my assumption is that the prediction was SB III but that the great game was the preceding AFL title game against the Raiders in which Joe threw for three touchdowns.
2. Namath was named the MVP of SB III, which leads me to believe that his performance during the game went beyond his stats. Before you tell me that the QB always wins the MVP - I'll trot out Trent Dilfer's name and the 2000 Ravens to assuage that notion.
3. Namath also had some decent throwing seasons, including 1967 when he was the first QB to break the 4,000 yard mark in a season. He was rookie of the year as well as a four time all-star.
4. Namath is in the NFL's hall of fame, despite throwing more interceptions than touchdowns. While he wasn't a first-ballot HOFer, he went in on his third or fourth year of eligibility.
So to me it seems that many of the NFL's observers view Namath as more important than just his stats or one great game. You can call it an inspirational career or one cut short by injury, but the consensus appears to be that he was a great player despite not having stats that shine in modern football's light.
