That's after Diamond had already called Chizik to tell him he was coming to Auburn. In the end, you really don't know. I remember in the mid-80s Dye was completely shocked when Brent Fullwood announced his commitment to Auburn.
To summarize the article and Diamonds decision....The answer is pretty straight forward...
1.He wanted a Family Atmosphere for his "home away from home"
2.He wanted a coaching staff , that he could "trust" what he was told by them.
3.He wanted to play "big boy football"

If you have to ask why I love Auburn so much...never mind
