Here's something I saw last night that's pretty relevant to how Dykes will probably practice.

Third entry down marked Dec 11 is titled "Mike Leach Passing Fundamentals."
The entire videos in interesting. Of particular interest is the "Routes on Air" portion at around the 15:10 mark. I've only ever seen Air Raid lineage coaches use this, but it seems highly efficient.
I hope they have open practices, I would love to see how the coaching staff installs the offense.
