Isaiah Jacobs, a running back from UAB and brother of Green Bay Packers RB Josh Jacobs, received a tryout invitation to the Packers' rookie minicamp. The Packers have been relatively conservative at running back given Josh's durability (929 yards, 13 touchdowns last season), making Isaiah's minicamp appearance a low-risk way to evaluate family prospects. This is standard practice in the NFL where teams occasionally extend tryout opportunities to relatives of star players.
