We all know that Denard is very difficult to game plan for. His speed and ability to break one off at any time give our offense a huge advantage. This has been discussed to death. There is, however, another advantage that Denard looks to be able to give us if he continues to perform at this level as we head into Big Ten play - a mental advantage.
This is a commen occurrence in sports - once the hype train gets going (especially on the worldwide leader), the build up to playing against the hyped player becomes so big that opposing players lose focus and over-anticipate. With Denard putting up video game numbers, his mere presence has the potential to get into opposing teams' heads.
If this continues, I can see opposing teams' defenses making stupid mistakes because the hype around Denard's unstopability gets into their heads. Not saying that good coaching cannot mitigate this, but I could see, for example, MSU's defense focusing so much on being the first team to shut down Denard that he will have a host of opportunities to find open receivers when MSU stacks the line on every play.
