In my own opinion, this is what I see from a preseason standpoint
1) the conference with the most parity would appear to be the pac 12; the race for the conference title has never been more wide open in my lifetime. I believe there are 4 legit contenders, but some may argue as much as six. Should be interesting.
2)it would be easy to say the SEC here, but looking deeper into this I think the Big 12 has the best chance of stirring up some serious chaos. If a couple of teams play spoiler or decide to knock off the big dogs like tcu/Baylor, things could get very hectic in an all out battle for the big 12 title and even let another conference in the door to the playoffs (the acc....or Norte dame)
3) very tough call here but I think the biggest disappointment will be the big 10. The reason I say this is because Ohio state can almost sleepwalk thru their schedule until they meet up with sparty two weeks prior to the conference title. Penn state will put up a fight but that games in the horseshoe and I don't see it being any closer than a 13-14 point game. The rest of the conference appears to be fighting for second place.... Kind of lackluster if you ask me, but someone beating the Buckeyes would certainly shock the football world.
4) I can't see any conference putting two teams in the playoff, but if it were to happen I would say the SEC has the best shot. Primarily because the writers love them, and they typically do play some of the hardest schedules in the country. That's all I got on that.
5) this one is to difficult for me to decide. I'll leave it as a tie between the SEC and Pac 12.... Remember I'm not talking about players, or talent, notoriety, schedules or any of that other stuff, just strictly the head coaches. I see the Sec has some great top half coaches but the bottom half is average in my opinion. The pac 12 seems to lack some of the big time big name coaches at the top half, but appears to have more "above average " coaches throughout the conference... Just my viewpoint
