Grantham met with the media on Tuesday and the first question was about his former team - Georgia - and what it will be like to take on the Bulldogs. Louisville and Georgia will meet in the Belk Bowl on Dec. 30 in Charlotte, N.C.
"I was out recruiting when it happened and my phone kind of blew up with what was getting ready to transpire," Grantham said. "I was excited for us to play another quality opponent. They are talented offensively. As a defensive player, you always look forward to challenges when you face a team that is as explosive as they are, so it excited me.
"We are looking forward to it and we know it's a challenge."
Grantham didn't want to get into making the game about Grantham vs. the Bulldogs, rather talking about his team's defense and tackling and schemes.
The veteran assistant coach noted it's "still going to get down to tackling. I don't now how much me being there is going to help, it's still football."
Grantham's defense has been stellar all season.
The Cardinals lead the nation in interceptions with 25 and rank fourth in third-down defense at 28.2 percent. U of L also is tied for seventh in sacks with 3.25 a game and ranked among the top 10 in a number of other categories.
