From today's "Give 'Em [Swear Word] Brigham" newsletter:
"As for Tuiaki, you could fire him tomorrow but I don't think you would see a difference. Talk to any defensive coach (off the record because nobody except for maybe Kevin Clune would say anything on the record) or any former defensive player and you will quickly learn that Tuiaki's scheme is mostly Lamb's scheme. The two have come together in recent years and work together on most things, but if BYU were to dismiss Tuiaki and keep Lamb, things wouldn't change. They just wouldn't."
The reason I wrote what I did yesterday is because I'm fairly good friends with a GA on the team, and while he hasn't ever come right out and said anything, he has made some implications. And I made some inferences. Interesting that Jeff (or whoever authors the newsletter) would send this, all but confirming my suspicions.
