You make it sound so easy, as if just recruiting faster guys in the secondary solves the problem.
That's not all there is too it.
If the front 7 are getting more pressure, the QB has to get rid of it quicker. In that case the DB's should be within range of the receiver and able to make a play. In addition, you have to always assume wide receivers are going to be more talented than your corners (otherwise the corners would be playing wide receiver) (and yes there are some exceptions like Deion) so your safetys have to be ready and in position to make a play.
You pull out the Akron clip but I can make a point out of that - Do you really think Akron was as talented as Tennessee? No way! They were better coached than Tennessee, that is evident by their performance. I've said it 100 times, Football isn't just about talent, it's about playing as a team and knowing your assignments. Yes at the top level the NFL the talent is so elite that it makes a difference.
But there are over 10,000 scholarship football payers in D1, there are 1,700 active roster NFL guys. In college it's not just talent, game plan and execution will win games more often than not.
l understand all that, but let me use an obvious example here.
trey burton's 80 yard td run. was that coaching? to a certain point in that play, maybe it is.
but, at the point where it's trey burton and marsalis teague, it wasn't about coaching.
it was about a player being so pitiful, not only did he not make the tackle, the runner didn't break stride. the defensive player had the sideline, he had the angle, and he wasn't bringing down earl campbell.
that player was a senior. that player had been coached by 3 defensive coordinators and who knows how many position coaches. so, don't tell me he wasn't coached. he had the opportunity to make as easy a tackle as he would ever get an opportunity to make and the runner never even slowed down going by him.
now, i am not going to go through the whole roster and i am not going to provide examples from throughout the season.
however, there are numerous examples where players have to go make a play. they have to use their speed, their brain, and whatever other abilities they have to make a play. and many times the players failed having nothing to do with coaching.
that byron moore interception clip is a perfect example. tennessee blitzed. it worked. the qb was pressured and made a poor decision. it resulted in an easy pick. the player who caught it had nothing but green grass in front of him. and he got cut off by an offensive lineman with relative ease.
so, yes coaching and playing as a unit, etc, etc, etc, all are important.
but, you can still see when individuals lack certain abilities despite what everyone else is doing.
