Last summer, Ed Orgeron and the LSU coaching staff gathered inside the Tigers football facilities for a presentation. It was to learn about the New Orleans Saints offense from their offensive coordinator, Pete Carmichael, who had coached with Orgeron when they were both Saints assistants in 2008.

Carmichael brought along a young and fervent offensive assistant, who at one point took over the presentation and captivated the LSU coaching staff with his command of schemes and strategies.

The impression lasted for nearly a year, and Monday, that assistant was formally announced as the replacement for passing game coordinator Jerry Sullivan, who retired in early January.
