A Hog's view of the situation...
Just wanted to give my two cents worth on the situation.
First, Gus Malzahn has coached at three different high-school classifications during his career and has won state championships at all three levels. His teams at Hughes and Shiloh Christian consistently defeated teams at higher levels often by embarrassing margins. His offense at Hughes (his first head-coaching job) did run a power I offense but he developed his current spread offense at Shiloh Christian in the mid-90's.
Most Hog fans realize that the jump between high school and the SEC is huge but yet many have been clamoring for the UofA to hire him for several years. He has published a book on his offensive philosophy and often spends the summer months on the lecture circuit (including stops at some NCAA campuses) explaining his system.
With all that said, it is understood that it is a HUGE risk to hire him as a coordinator. But most fans are willing to take the chance because most of us feel that we have no chance for a championship running HDN's vanilla attack. If you watched our team on a consistent basis, you'd notice what we've been seeing since HDN's first two years with Stoerner at the helm: passes in the middle of the field are non-existent, running the ball on 3rd down and 10+ yards to go, running 5-yard patterns on 3rd and 10, all timeouts wasted before the end of the 1st qtr (see the Hogs/Tide game in Tuscaloosa this year), no quick slants over the middle, fans cheering an incomplete pass downfield because they're so rare......
Personally I'm satisfied with the move. Either you can coach and gameplan or you can't. I'm confident that Malzahn will quickly prove that he can. To me, the big risk is whether our offensive line coach, Mike Markuson, will work well with Gus. Markuson has had much input into the offensive gameplan in the past and now he'll have to take orders from a former high-school coach. How well those two work together will tell the tale whether this experiment succeeds or not.
Later.
