If Jefferson is injured, then Jawan Jennings would be the next man in... Jordan Addison would move to like the wide receiver one role and Jennings would operate as sort of a wide receiver, too

Jennings is Jefferson handcuff with WR upside if JJ injured

Jawan Jennings is the next man up if Justin Jefferson is injured. He would operate as a wide receiver in the Vikings offense with increased opportunity, with Jordan Addison moving to the WR1 role. This makes Jennings a handcuff worth monitoring given Jefferson's injury uncertainty.
