"From the year before Cahoon arrived to 2012, BYU's CPD rate has more than tripled, while the drop percentage is a little more than a third of what it was in 2010. None of the six WRs in 2010 had CPD rates higher than 7.0, while in 2012, all nine WRs had CPD rates of 6.7 or higher. Through 2010 and 2011, only three of 12 WR performances featured drop percentages in the single-digits, while in 2012, eight of nine WRs have drop percentages under 10."
So.........basically in 2010 there was a drop for ever 4.2 catches, (29 drops to 123 catches) IN 2011 that improved to a drop every 5.1 catches, 30 drops versus 154 receptions. In 2012 it improved again to a drop every 13.1 catches, 14 drops on 183 receptions. To me that is great progress as a WR unit.
