I don't think Shane is that good at making the 5-10 yard throws in tight-ish windows that Sam does pretty well, which is a problem in this offense. He used to be able to drop deep balls on a dime and I doubt he has permanently lost that ability. Frankly I think the strategy yesterday was pretty much right on for making the best of his skillset and the pieces we have around him - hand it off a lot to sustain drives and force them to defend the run, then look for big home-run shots downfield every so often and hope that one out of every X attempts nets us a big play or a score.
Although I think we could probably run him more too (I know we did it some, but still). After all, Tom Herman's most celebrated accomplishment was a season spent murdering QBs and just plugging another one in to do the same thing whenever one went down. I guess maybe we did see LJH did get a couple of auditions for that Greg Ward/Braxton Miller WR/QB role.
