Vaughn rushed nine times for 18 yards, secured his only target for nine yards and ran back two kickoffs for 31 yards in the Buccaneers' 34-3 preseason loss to the Titans on Saturday night.
With Ronald Jones and Leonard Fournette idle, Vaughn comfortably paced the Buccaneers in carries but could hardly get anything done with them. He did capitalize on his only opportunity as a receiver, but his 15.5 yards per return average on kickoffs also left plenty to be desired. Vaughn received praise from head coach Bruce Arians after the preseason opener against the Bengals for his overall play, particularly on special teams, but the second-year back still looks like a clear-cut No. 4 option who will struggle to see many opportunities from scrimmage as long as all of Jones, Fournette and Giovani Bernard are healthy.
