I like this logo as a helmet decal. My biggest beef with the current one is it's so static -- perfectly square 2D images don't look right on spherical objects like a helmet. The proposed M-State logo (option #F) is dynamic and has a little bit of a forward tilt to it (or backward, depending open which side it's on). You can tweak the "M" a little, but overall I think it brings MSU into the 21st century branding-wise.
Drawbacks: because it is so stylized it may looked dated in a decades time. Also it so different than the current logo, it will make those logos feel dated almost immediately.
