Former Ohio State football star Jim Stillwagon is suspected of shooting at a pickup truck on a highway ramp and later striking the driver with a handgun, causing it to fire a bullet that grazed the man's head, after a road rage incident that spanned about 14 miles, police said Monday. The college Hall of Famer, a middle guard who helped the Buckeyes to a national championship in 1968, was jailed on a felonious assault charge and had bond set at $350,000 in municipal court in Delaware, north of Columbus.
