Alabama and Clemson have been the best two teams this season, and two of the top teams over the past several years.

As of now, it seems likely that the Crimson Tide and Tigers could be playing for the national championship in January.

So, who currently has the edge for that potential matchup? Kirk Herbstreit discussed that on ESPN’s “Get Up!” on Tuesday.

“I still would have to get Alabama a little bit of an edge, but the defense overall for Clemson has been about as good as advertised,” Herbstreit said on the show, per 247sports. “I think we’ve been trending toward that potential matchup since late August, and clearly those are the top two teams in college football right now.”

The Crimson Tide are undefeated, but they aren’t blowing out teams quite as much as they were early in the season. The Citadel played them close for a half before Alabama pulled away for a 50-17 win.

The Tigers are also undefeated as they have rolled through most of their ACC competition.

“They have not been the same dominant team, looking like a video game team watching them play,” Herbstreit said of Alabama. “The other team, Clemson, is gaining momentum and peaking at the right time. With that being said, you’ve got to remember that Nick Saban and his team — he knows how to get them ready.”

Alabama ends its regular season against Auburn on Saturday, then will play Georgia in the SEC Championship Game. Clemson plays South Carolina on Saturday, followed by a matchup against Pittsburgh for the ACC championship.
