It depends on what era of Sumlin. He never really had a set offense and took a CEO style approach. 2012 and 2013 were very similar. I think 2013 had a bit more pistol with an h back. Those offenses beat Bama, and the one that didn't still scored 42 points. 2014 we were still passing the ball a lot but tweaked a things formation wise and a bit concept wise. A lot more y-off type looks and such. 2015 we tried to throw RPOs in there and focus on running the ball more with y-off TEs and H backs.
If we went air raid today it most likely wouldn't look anything like what we ran back then, the offense had changed so much. At minimum I would assume it would have a y off TE and we would run counter as opposed to being a strictly zone team. Outside of Leach all air raid systems have added that as an answer to the tite front. We never did back then because Alabama and Georgia type teams were still running over/under fronts as their base nickel package. I don't think they added their mint package in nickel until after 2015.
Any man who can hitch the length and breadth of the galaxy, rough it, slum it, struggle against terrible odds, win through, and still know where his towel is, is clearly a man to be reckoned with.
