The defense for Knoxville boys soccer is coming along. Coach John Smith says senior Jason Ryan returns as one of the defenders. Also back on defense is Brandon De Heer, and senior Tyler Worrall is out for the first time in his high school career. Smith says there will be a lot of speed in the defense and hopes to fill in midfield position by Tuesday’s season-opener against Carlisle. Smith adds one concern that he has is a lack of depth. He says the starting 11 are pretty solid, but the second unit is very inexperienced.
