Bayou Bengal is closer...but I think your stat doesn't count the ones that were fair caught or something.
Since Bayou Bengal came so close, and apparently not many are interested...I'll give it up. "0.9 - That’s the yards per punt return LSU opponents averaged a season ago, the second-lowest total in the SEC to Florida’s 0.6 yards/return. To put it in perspective, the Tigers punted 63 times in ‘09, and those punts were returned for a total of 57 yards. Punter Derek Helton returns in ‘10." Per Tigerrag. Lots of fun facts on there as they are counting down the days...16 to go.
