Knoxville, Tenn. -

Tennessee's hopes of competing in the Southeastern Conference this season start at the line of scrimmage.
    
And they just might end there as well.
    
The Volunteers began preseason camp Friday night without any offensive or defensive linemen who started more than three games last season. Tennessee is the only Football Bowl Subdivision program replacing both its entire starting offensive and defensive lines from a year ago.
    
Tennessee's new offensive line must replace a group that featured first-round draft pick Ja'wuan James while allowing just 23 sacks over the last two seasons, the fewest in the SEC over that stretch. The defensive line is trying to boost the pass rush of a team that recorded the SEC's lowest sack total each of the last two years.
