Last year Tennessee struggled to stay healthy on the offensive side of the ball but the Vols were unusually healthy on defense, which was amazing considering the number of snaps most of those guys had to play. This year Tennessee had greater depth coming into the season, but at the halfway point that depth is being tested on both sides of the ball.
But we're also seeing an emerging youth movement, where more talented freshmen and newcomers are slowly making their way into the rotation. Add in what should be a softer second half schedule, and there are plenty of chances for young players to make their mark on 2015 in preparation to do more of the same in 2016.
