Many of the counterarguments in this thread are very well made. However I do have some counterpoints...
To those who say that Hansen will get injured running the option, did you see the Cal game last year? Did we stop their DEs once? Its hard to see how he could take more of a pounding.
I agree that it is hard to go from good to great with an option attack. However, at this point, we aren't even good. In the first quarter of the aforementioned Cal game it seemed that we couldn't run a play without a penalty. Had we ever practiced? That said, given the the intensity of Spring ball, I expect us to be ready for each and every game this year.
As for being unable to get good recruits for the option, our recent performance likely has more influence than does the type of offense. Also, didn't we lose Berglund due to the pro set (his current difficulties aside).
Does the plan for going from bad to good need to be the same as that for going from good to great?
