Yes, clearly it should be Clifford. His Passer rating, QBR, and ANY/A for the season are higher than Love. Dontayvion Wicks is a bit behind him in those categories, but he should be the backup and Love can be QB3.
Nevermind Clifford and Wicks have each thrown ONE pass, at least neither is a halfbreed or whatever nonsense is being spouted at the moment.
