1. A high-powered, most likely passing-emphasized offense is necessary to win a championship If we didn't prove this this year, I don't know anything. We've been saying for years that if we ever got an offense, we would win another championship--and for once we were right. I believe that this is only a recent development, though. A number of teams in the 2010 decade won with a run-based offense (2010 Auburn, 2011 Alabama, 2012 Alabama, 2014 OSU). But I think we've officially crossed the threshold into a new era. When you watch good teams play each other, the better offense always seems to win, and great defenses seem to do poorly against great offenses (Clemson, Auburn, Florida, all struggled against us). The good thing is that we have a coach that gets this. 2. A good pass rush is now more important than a talented secondary in stopping the pass We had the most talented secondary in the country this year, and our passing defense was pretty middle of the road. I think this is because of our lack of a pass rush early on in the season (although later it picked up). In 2018 Clemson dominated Alabama's top-tier offense behind one of the best defensive lines in college football. Hell even 2019 Clemson showed us this in the national championship: when they got to Burrow, we didn't move the ball; when he had time, we did very well. I think you will see that the only way to stop the new passing schemes that are extremely likely to flood the top-tier teams will be to get pressure on the QB. Bo Pelini has entered the chat. 3. Line Backer is becoming a significantly less important position as a result of (1) and (2) Because the spread is the way of the future, we see more 3-4 WR sets, and LBs do not match up well with these personnel. You can't have a LB covering a WR or a TE very often without risking getting burned. There were very few playmaking linebackers this year, and I think this is why. While the debate has usually been 3-4 v. 4-3, I think the debate now becomes 3-3-5 vs. 4-2-5. 4. Speed is still king Very similar to point (3), but when you are spreading the field, it becomes significantly more important to be able to cover a larger area of the field. We also had one of the fastest teams in the country (especially on defense) last year, and I think it really helped our defense succeed when it needed to against some of the high-powered and lateral offenses. I think you also saw Ohio State dominate the slow Big-10 defenses and struggle against a speedier Clemson defense that could match up with them. Speed is not going anywhere. 5. College Football is now a top-heavy arms race The distance between the haves and the have-nots is getting bigger than ever before. The latest recruiting rankings demonstrate that a handful of teams are getting the top tier talent in droves and are running away with games against lesser competition. I think this point is really proven by Oklahoma's performance in the CFP the past three years. Every year, they are the best team in the Big-12, but they don't have the horses to compete with the top teams in the playoff because they haven't recruited quite as well. We've also seen the coaching carousel begin to affect analysts, and teams are following Saban in grabbing as many coaches as they can to act as analysts hoping to fine the next Joe Brady. Teams are also locking in coordinators at higher salaries than ever, and again, it's only the teams at the top. I suppose the other point that comes along with this is that it’s no longer ok to lose to good teams in the SEC. Again, I’ll point to Alabama, who would have been on their way to the playoff themselves if they beat us, but they lose to us, and things looked a lot different after. I know Tua’s injury had some to do with that, but one loss in the SEC will now be a difference maker every year.
