The spring practices is a time for discovering the quality of players on the roster by letting them get reps.
This can make the quality of the play rather raged as it did this year. Yes the offense is more a work in progress than the defense. Is that a concern? Yes, but it is way too soon to say "heaven help us the offense stinks". Still with Hoover back this summer and the offensive line settled in, things will be better. However, no I don't think the offense will be as strong as I would like it to be this season, at least not initially.
