no. if u can get 3-4 very good corners, 2 safeties who can cover and tackle, and 8 dl who can come in when subsitute who can all get to qb u can have a dominant d in college.
the thing is u really need to find 3 corners who in 80s would of all been number 1 cb. the nickle guy has to be a chris harris type like the denver broncos use who is quick and fast. then it all comes down to being able to penatrate get pressure with 4 and keeping in lanes so mobile qb's can't just skip away.
also u need a dc unafraid to get after qb's , he has to be willing to at times put his corners on an island and send 5-6 guys at a time. the spread offense has its challenges to stop but it can be done.
so while dominant d isn't thing of the past it will take a team who can get speed everywhere to do it. bama had a great d but a great qb just made them avg. because they don't have that dominant cover corner. and really in today's college u need at least 2 of them against teams like clemson to shut them down.
Not sure if this post was tongue in cheek but that is nearly impossible to do, bama with unlimited resources and best coaching still got ripped and had to gamble with onside kick because nick admittedly had no faith in his gassed defense built specifically for this type of offense..
Saban's defense is not built for that kind of offense. Saban's defense is big and powerful, meant to keep teams from running all over them. Look at the difference between the Mich St game and the Clemson game. Clemson is fast and all about getting the ball to playmakers and letting them do work. Mich St is a more of a grind em out offense. Saban struggles most with offenses like Clemson's, but doesn't see them very often in the SEC.
Saban very clearly stated they made detailed changes to adjust to uptempo offenses. Houston's coach opened his doors to saban in offseason where Saban humbly bought his whole staff and then Houston's came to Tuscaloosa, also it has been published multiple times that They had Dlineman drop weight, he recruited more speed rushers, He moved cover corners to safety, he adjusted packages, he had lineman ready to be subbed in and many more adjustments to adjust to uptempo spread offenses. Believe me he wasnt doing all this for pro style guys. Even with all that, still got lit up.
I say that to say even Nick with all resources, all offseason to tinker, with adjustments made, and an endless supply of top flight recruits, the top defensive mind in college ball today cant keep up. Sabans defense is big and powerful and fast and talented, its whatever he wants it to be. Its the best in land and still got lit up
