Aggie, I will take it upon myself to rank those rigs:
Oklahoma: OUTSTANDING. Appropriate emphasis on the national titles. Logo prominently and tastefully represented. Unobtrusive use of the sponsor (nike) logo. Also, best rig--that thing actually looks like it goes with the trailer. 10/10
LSU: Freakin' sweet! Love the helmet as the centerpiece of the mural, but the best part of this rig is the tiger eyes and the relief of Death Valley ominously in the background. Add in the national title trophy and you have a winner of a trailer. 9.5/10
Alabama: Not terrible, but not epic for the national champs. The "less is more" approach falls somewhat flat with the players just standing there. Major plus, however, for the "we live it" slogan--just wish it was more prominently displayed. 7/10
SMU: weaksauce. Ambiguous background with the generic logo makes this rig look like it was designed on a Windows 98 paint program. 3.5/10
ohio state: **vomits** ok, despite the unspeakable evil this rig represents, it's actually a better use of the keeping-it-simple approach Alabama tried to use earlier. I like the take off of the ohio state helmet, and the entire truck has a crisp, clean look to it. 8/10. Now excuse me while I go vomit again.....
texas tech: An "aight" effort. Most tasteful use of an alternate logo of the above examples. Could've used a more imaginative font for the white lettering, however. And while I like the use of the rig, it kinda looks like they just put oversized stickers after a while. 6/10
Ole Miss: Although the paint scheme is really elaborate, the whole truck comes off as somewhat generic. A good effort, but really not in the same class as some of the better trailers out there. 6.5/10
