Utah trolls Caleb Williams writing ‘F--- UTAH’ on fingernails in Pac 12 Championship blowout

Heisman favorite Caleb Williams sent a clear message to the Utah Utes before he and the USC Trojans took them on in Friday's Pac 12 Championship.

On his fingernails, he wrote, "F--- UTAH," with one letter written on each finger - aside from the thumbs.

After the Utes blew out the Trojans, 47-24, to take home their second-straight Pac 12 title, of course the Utes had to answer back.

The Utah football official Twitter account had a ton of fun trolling Williams and replaced his dig with a quick reminder.
