Maybe conferences have different rules. I remember a Purdue-Minnesota game just a few years back where after Minnestoa tied up the game with only seconds to go, Purdue got the kickoff and completed a long pass to past midfield, in-bounds, with only 1 second left on the clock. They rush the FG unit on and snap as soon as the ref signals ready for play, in order to get the play off before time expires, and kick the winning FG. The Minnesota bench was whining that Purdue couldn't have gotten the snap off in time.
hmmm....
what year?
