I think the run game thing gets overplayed. Of course it's important, Kirk himself brings it up constantly as priority one. But then he also uses the phrase "balanced offense" quite often.
In 2015 we didn't have a 1,000 yard rusher - yet won 12 games.
In 2016 we had a pair of 1,000 yard rushers and won 8 games.
I just think it is too simplistic to say every off season, "our running game will determine our success". Of course we want a good running game, but I remember 2004 when we had a shit running game and beat LSU and finished ranked in the top 10. Hell, this past season we beat a different SEC school after rushing for negative 15 yards. Too many other factors to lay the season at the feet of one unit.
