Harrison signed as an undrafted free agent with the New England Patriots after the 2013 NFL Draft and was placed on the reserve/non-football injury list with a broken foot. He never saw any time on the field last year, but he had recently participated in workouts this offseason with New England so his health is not an issue. The Patriots recently released Harrison to make room for linebacker James Anderson, but the timing came right after Harrison was late to OTAs (organized team activities).
Harrison has great size at 6'3, 230 pounds, and he immediately becomes the biggest target on the Chiefs roster at wideout. (Dwayne Bowe is next at 6'2, 221 pounds.) Harrison's sized proved valuable at Rutgers where he finished with strong red zone numbers given his overall production. Harrison had 107 career receptions, but 18 of those went for touchdowns.
Harrison hasn't always lived up to his measurables, and has had some ups and downs throughout his career at Rutgers. Still, his blend of size and athletic ability will result in some team taking a flier on him.
In his senior year at Rutgers, Harrison had 44 catches for 583 yards and 6 touchdowns.
