Not a lot of journalistic integrity in that article. It's really not that complicated to have 3 teams play everyone in division and one less cross-division game and the other four teams play one less division game and one more cross game. It's arithmetic, not calculus.
As far as the division winner--let the overall conference record decide it, as it does now. The conference can ensure for the next few schedules (in case a 14th isn't added soon) that any two schools that are likely to be serious contenders for the division, conference, and national titles play each other in that year. The likelihood of west division opponents not playing each other in a year they otherwise go undefeated is slim, and the argument of "we played so-and-so this year you didn't" is lame--LSU has had Florida every year since the expansion while the rest of the west just rotates through them, and the same goes for Auburn vs Georgia (until Georgia stopped being as dominant).
