Yes,Alcoa was very young team. Four freshman starters in the championship game.
Going into next season, Seniors #23,#21,#40 & #4 will be big loses on defense. Great players.
Freshman defensive starters #98,#12, will return even better next season. Freshman players #7 & #42 may find more playing time at LB with #30. #33 will be back from injury and will be a big part of the defense.
Not as many holes to fill on the offensive side. Alcoa will be loaded in the backfield and should have an even better passing game next season.
