He's a mountain of a man, but when it comes right down to it, tight end Freddie Jones would rather dash than mash. An adequate blocker with soft hands and a smooth, deceptively swift stride, Jones led the Chargers last year with 57 receptions, the most by a Chargers tight end since Hall of Famer Kellen Winslow had 64 in 1986. Jones's numbers should rise in '99: The Chargers lack a big-play wideout, and new coach Mike Riley's offense favors high-percentage passes underneath zone coverages. "You don't normally think of a tight end as being a go-to receiver, but this guy is," Riley says. "We plan to build on our strengths." Quarterback Jim Harbaugh, a master of play action who leaned heavily on tight end Ken Dilger in Indianapolis, is excited about the potential of Jones, a second-round pick out of North Carolina in '97. "If this guy's not going to be a star in this league," Harbaugh says, "then I've never seen one."
