Thanks.This makes for a good discussion. I think you have some good points.
But, I think they were probably trying to imitate the best (Bama). So, he hires a Bama guy, who was due a promotion. If you remember at the time, just about all the "experts" thought Sal was a good hire. He knows Smart's defense, and maybe, given time he could be a good coordinator. Lots of teams struggle the first year of change to 3-4.
Also, there have been some extenuating circumstances in the last couple of years in linebacker recruiting. Santos and Peters switched on us last second, hurting potential depth. Also, we lost Christian Harris to a knee injury and Bynum for the year as well, not to mention Maggitt has been a shell of himself, since the turf toe injury in the NC State game.
The buck stops with the coaches, but they have had some challenges to deal with in the 3-4 change this year.
On the flip side, the argument could be made, that there are always challenges, and the best coaches find ways to motivate their players to rise to the occasion.
