In a release Thursday, the hall said the number is on pace to represent one of the largest contingents of Hall of Famers to attend the annual enshrinement ceremony.
Members committed to attend include Troy Aikman, Terry Bradshaw, Dick Butkus, Len Dawson, Eric Dickerson, Dan Dierdorf, John Elway, Joe Gibbs, Michael Irvin, Jim Kelly, Ronnie Lott, Gale Sayers, Lynn Swann, Kellen Winslow and Buffalo Bills guard Joe DeLamielleure.
"I'd walk from my home in Charlotte to Canton if I had to," DeLamielleure said.
He has not missed the ceremony since he was enshrined in 2003.
The 2008 inductees will be former Washington Redskins Art Monk (wide receiver) and Darrell Green (defensive back), Kansas City's Emmitt Thomas (defensive back), New England's Andre Tippett (linebacker), and offensive tackle Gary Zimmerman (Minnesota, Denver).
