Evaluating position groups this year vs. last year

Offense improves thanks to better o line philosophies which leads to a better run game and more time for richardson in the pocket. Richardson more experience at qb. I see no way the defense improves with all we lost imo
Seriously? I call horse hockey--the line will be improved by having Shaban Dika healthy, and having tackles playing tackle, instead of guard. Plenty of improvement available right there.

Oh yeah--I could mention that Ethan Tuftee was playing on one leg half the season--but that seems like overkill.
