Several college football one-two punches can hit you in the mouth for a knockout.
There are offensive skill-position duos who are like the gridiron's versions of tag-team wrestling tandems who gang up on the opponent and barrage them before they know it. Others are delivering blows from the defensive and can change games on a dime.
All of these duos have shown promise, even if some of their potential is just being realized. The criteria used for these rankings is the ability of the tandem to team up and wreak havoc on the other team and take the game over.
