When the North Carolina Tar Heels battle to keep the Victory Bell for the fourth straight season, the ebb and flow of momentum are much more pronounced.
Just think about 2019 versus Duke: one of only two career fumbles lost by Javonte Williams happened in the closing minutes of that game. Carolina had just a three-point lead with too much time on the clock for the archrivals.
Momentum swung in their favor, and the Blue Devils marched 92 yards down the field to the UNC two-yard line on the brink of a final second win.
