It's spring cleaning, which means putting away the football charts that have been collecting on a dining table no longer used for dining.
Among the notes:
> The Rainbow Warriors were in formations involving three or more receivers on 71.1 percent of their offensive plays in 2013.
> They were in five-receiver sets six times.
> They played at a relatively fast pace, averaging a play every 20.3 seconds.
> They are ranked 38th nationally in explosive drives at 15.8 percent, according to the Freemau Efficiency Index. That's a system that tallies full drives averaging at least 10 yards per play.
> They had explosive drives on 29 of their 184 full possessions (that were not abbreviated by the ends of halves.)
> In the final nine games, when quarterback coach Jordan Wynn took over as the lead play-caller, there were explosive drives on 26 of 145 full possessions, or 18.4 percent.
> The defense relinquished explosive drives at 12.9 percent.
> Opponents lost fumbles on 35.7 percent of the Scott Harding punts they tried to return.
