But first, news regarding Pardon the Interruption:

The video above, the inaugural PTImeline, debuted on Grantland.com three weeks ago. The 15-minute video offers a retrospective of LeBron James’ basketball career from high school to the present through 10 years of Pardon the Interruption conversations between hosts Tony Kornheiser and Michael Wilbon. The compilation has received over 270,000 YouTube views at the Grantland Channel.

Tomorrow, a new PTImeline will document the past decade of Notre Dame Football.

The 30-minute Pardon the Interruption Special: Notre Dame Timeline will air Tuesday, Dec. 18, at 7:30 p.m. ET on ESPN. The video will also be released online via Grantland.com.

Beginning with the decision to fire head coach Bob Davie in 2001 and culminating with this season’s number one ranking and berth in the BCS Championship Game, the new PTImeline will document various Fighting Irish coaching hires (George O’Leary, Ty Willingham, Charlie Weis and Brian Kelly), the controversial “Bush Push” in the 2005 USC game, and the Declan Sullivan tragedy in 2011.

PTImeline is the brainchild of longtime PTI executive producer Erik Rydholm and coordinating producer Matthew Kelliher.

“We’ve been knocking around the idea for years as a way to breathe new life into old content, but never had the people to pull it off,” Rydholm said.

Fortunately, a handful of former PTI employees and interns – Justin Bolman, Mary Moczula, Brad Morgan, Charles Peach, Clay Skipper and Megan McHale – are part of the Dan LeBatard is Highly Questionable staff, which is also based at the ESPN offices in the Washington, D.C., bureau of ABC News. Rydholm had them pull and arrange clips during some of the non-show days for DLHQ.

Rydholm also credits Grantland’s David Jacoby for making the project a reality by editing rough cuts, preparing the videos for air and supplying graphics and other visual elements.

Safe to say, with the excitement over the Fighting Irish reaching a fever pitch, tomorrow’s premiere is sure to generate some buzz.

Rydholm said there is the possibility for more PTImelines down the road.
