Football Outsiders has had some statistical analysis recently of the best and worst quarterback completion percentages from 2006, controlling for some variables.
What they found was that Charlie Frye was one of the ten most accurate passers in the league. That held when they controlled for dropped passes, and when they adjusted completion percentages based on how many short (and typically more accurate) passes a QB threw.
The end conclusion was that Frye was extremely accurate with his short passes (nearly 90%), so they decided to remove short passes from the analysis all together, at which point Frye dropped out of the top ten.
What does this all mean? Not a lot. We all saw how well Frye was doing at hooking up with Winslow on the 2-4 yard pickups.
What does make me optimistic is that reports are that new Offensive Coordinator Chud is implementing an offense with alot more shorter, timed passes. Combined with Frye's skills on the short passes, this could be a good thing.
