WATCH: Keenan Allen roasts Stephon Gimore with double move on TD

Stephon Gilmore has been one of the best cornerbacks in the NFL all year, but on Sunday he made an epic mistake against the Los Angeles Chargers.

The cornerback bit hard on a double-move by Keenan Allen, darting to the middle of the field instead of staying outside to cover his third of the field. His epic gaffe left Allen wide open for the too-easy touchdown.

This mistake allowed the Chargers to tie the game up, 7-7, in the first quarter.
