I never understand why Tennessee never has a dominant Oline under Fulmer. He was suppose to have been a good offensive lineman in his day.
Quality of a player is usually inverse to their quality as a coach. There's a variety of reasons for this, but I'd argue the biggest one is that the best tend to both work hard and have great natural talent. The worse players need to focus on the most basic techniques as much as possible in order to hang on, and they tend to impart a great deal of that fundamental knowledge to their players.
That said, Fulmer has overseen some very good players and lines. Charles McRae, Jeff Smith, Bubba Miller, Kevin Mays, Cosey Coleman, Chad Clifton, Trey Teague, Jason Layman, Scott Wells, Will Ofenheusle, etc.
But if you look at who goes onto the next level since Fulmer first got back, you'll notice a staggering decline since roughly 2003. The talent most certainly is there, but everything I've seen points to a complete inability or unwillingness on the part of Greg Adkins to actually properly instruct the basic fundamentals of blocking. And
that is inexcusable. For a position coach (at the most important position) to wing it like this is beyond absurd.
Back to my first point, I was a terrible player. And so the inverse of that would be....well, either I'm a great coach or simply another loudmouth with an inflated ego who thinks he knows what good football looks like.
