Michigan was a very bad inside zone team again vs PSU

Michigan had much more success with their power and gap plays. They also finally put some guys in motion (still not nearly enough) and that had success as well. Is the IZ a permanent byproduct of hiring Frey, Pep, and Scot Turner or do you think at some point Michigan will realize it's simply not working (sans the IU game) and scrap it all together? As Brian said in his game recap Michigan "is caught between two different approaches on the ground." It just feels like all the clever gadget plays from the first two years and Harbaugh's Stanford teams are gone and there is no identity on offense. I realize some of that is magnified with the OL and QB issues, but there is a difference between having an average offense and the current one which is teetering on total ineptness.
