I don't think anyone disputes the lack of talent issue. I likewise surmise that most people point to the same person as the cause of that.
However, what you cannot do when coming into a situation like this is screw up your first asssistant hirings. Because that compounds the problems instead of solving them. Yet, this is what happened. Especially on offense where the parts were mismatched from day one.
Watson wanted to run a pro-style, WCO.
Wickline wanted to run zone. Period.
Les Koenning had last ran Dan Mullen's spread.
The decision was also made to keep Bruce Chambers (who liked to do whatever it was he did).
And then there was Strong himself who had his own influence on the offense (conservative playcalling, rely on his defense -- this drove UL fans nuts when they had Teddy B. and some pass-catching talent).
Did any two of these coaches share the same offensive philosophy? Our offense was a crazy quilt of coaching beliefs.
Less than a year later, we decided to switch offenses but determined that Watson was still the right coach to do that?
Choices made have consequences. How long will the effects of these coaching choices last?
