Spurrier seems to be largely forgotten as a player these days. I guess the way people overlook his skills and accomplishments on the field is understandable due to the passage of so many years. But he was a 2-time AA and a Heisman winner who happened to throw a very crisp, accurate pass - especially for the times in which he played. His touch and accuracy and arm strength were on a level similar to that displayed by Leak. I would rank them 1A & 1B.
The game has changed greatly and completion percentages have gone way up over the decades - due in part to the short passing game becoming a staple of modern CFB. But some of the guys that excelled back in the day are still great, but everything looks worse in black and white, according to Paul Simon at least.
