While my S&P+ college football team ratings include quite a few components, projecting the ratings in the offseason is a simple process. There are three primary ingredients: a team's returning production, its recent history and its two-year recruiting rankings.

This answers three key questions: How well has a team done recently? What talent has it lost from last year? And how good are the players replacing the lost talent?

I've posted each of these factors:

To come up with preliminary projections, I create projected S&P+ ratings based on each factor -- recruiting impact, returning production*, and recent history -- and then blend them together. The projection based on returning production gets the heaviest weight, followed by recruiting, then recent history, which only carries a little bit of weight.

* Note: the Returning Production ranking you see below is based on the impact of returning talent on last year's S&P+. So while LSU is No. 1 in the amount of its returning production per the link above, the Tigers rank third below partly because Clemson and Alabama were that much better last year.

Here are the preliminary projected S&P+ ratings for 2016.

Top 2? Maybe top 3.

Alabama and Clemson were easily the two best teams in college football in 2015, and with what each returns -- Bama brings back much of its absurd defense, and Clemson's offensive trio of sophomores (Deshaun Watson, Wayne Gallman, Artavis Scott) is now a trio of juniors -- it's easy to start with these two again in 2016.

I assumed that's who would be projected at the top ... and I was mostly right. LSU butted its way into the party, though.

The Tigers return virtually everybody, recruited well once more, and get an extra boost from the formula's use of five-year history. Granted, that means they're getting a small lift from the 2011 team that has long since departed, but their demise in the years since 2011 has been overstated.

They were an outstanding team for much of last season, barring a three-game funk that knocked them to ninth in S&P+. But they still finished ninth! And they return more than anybody else in the top 10.

Yes, they have questions to answer in the passing game. But here's where I remind you that quarterback Brandon Harris was a true sophomore. Sophomores not named Deshaun Watson tend to play like sophomores.

The ACC's making moves.

The Big Ten finished second behind the SEC in last year's S&P+, but with Ohio State and Michigan State regrouping, the conference is projected to regress. The SEC's offenses, meanwhile, will be far more experienced on average than they were, and of course the SEC gets the requisite recruiting bump. The conference's lead should increase next fall.

But look out for the ACC. Not only did it make a lot of impressive coaching hires, it also returns quite a bit of last year's production.

Projected conference S&P+ averages:

SEC (12.8, up 2.8 from 2015) ACC (9.2, up 2.5) Pac-12 (8.3, up 1.4) Big 12 (7.7, up 2.6) Big Ten (7.0, down 0.4) AAC (-1.4, up 0.7) MWC (-4.5, down 0.3) MAC (-5.8, down 2.2) Sun Belt (-8.3, down 0.8) Conference USA (-8.3, down 0.2)

Clemson and FSU both project as top-five teams, and five teams project between 20th and 32nd. More importantly, only one projects worse than 70th (Wake Forest, a decent 74th!). The ACC's strength has been its depth, and next year it could have especially impressive depth and two national title contenders.

Wait a second ... is that Washington in the top 10?

Yep.

The Huskies won last year's "mediocre record, strangely impressive S&P+ ratings" award*. They finished just 7-6, but they played really well in one particular loss (Oregon), lost two other games (to Boise State and California) by six or fewer points, and played at the 91st percentile or higher in six of seven wins. Very few teams played at an elite level more than that.

UW was also young as hell. That made for an inconsistent product, but it also means the Huskies return almost everything. That's all the numbers need to see.

Too much, too soon? Maybe. But Chris Petersen's rebuilding project appears to be a year ahead of what I anticipated.

Washington's presence in the top 10, by the way, allows me to whistle right on by Tennessee projecting ninth. NOTHING TO SEE HERE.

* Previous winners were almost guaranteed to see their records improve the next year, often by quite a bit.

The 2016 Pac-12 race could be fascinating. Five teams project between eighth and 18th, with just 2.3 points separating them -- two in the South (USC, UCLA) and three in the North (Washington, Stanford, Oregon).
