Jefferson could influence Vikings QB competition through his preference for ball placement and tempo.

Jefferson is positioned as a potential determining factor in the Vikings' quarterback competition between J.J. McCarthy and Kyler Murray. The source notes that Jefferson challenged the quarterbacks during mandatory minicamp to be better, specifically wanting a quarterback who can deliver the football consistently and on time. Jefferson has never been a diva or forced personnel decisions, but the source argues it's a non-zero proposition that he could voice a preference to coach Kevin O'Connell about which quarterback gives the Vikings the best chance to win, given his status as the most respected player on the roster.
