Comparing the years since Kirby has been here (not counting year 1), this year seems to have more unknowns heading into Spring practice than the prior years. OL, DL, QB, RB. When Kirby says it will be a true competition in Spring and Fall practice, this year it appears that will be the case at many positions. Unknowns not only in who will be the starters, but also what is the realistic ceiling for the coming year for individual players and the team. Will be interesting to see who starts in Knoxville (considering the first two games will still have a few "moving parts").
