Janoris Jenkins

Agreed, if we're talking about the best receiver. But, say we play the Vikings in the first round of the playoffs. You have to account for Diggs and Thielen. Probably best for Lattimore and Apple/Williams to handle whichever one ends up on their side of the ball. Then Jenkins would need to lock down whoever is lined up as the third on the line option, while Gardner-Johnson/Bell make sure Cook doesn't kill them. My uneducated perspective is that having "Rabbit" eliminate one option completely would be the best way to get him involved at such a late date.
I only say this because Jenkins (reportedly, according to talking heads on Fox 8 this morning) has played like 95% of his snaps at DB as an outside corner and I think Lattimore has the speed and hips to play the slot which he'd be doing as a roamer type DB covering third receiver wherever he lines up.
