Two weeks in, and preseason opinions are changing as fast as quarterback depth charts.

Some positively, others not so much.

Who are the biggest surprises in the SEC? That’s something we’ve been discussing.

Connor O’Gara, senior national columnist: You know when you spend all offseason hearing about how great a middle-of-the-pack team is supposed to be the following year, and you’re reluctant to buy in? That was me with South Carolina.

Well, I’m buying in now.

Why? Jake Bentley is a big reason for that. It’s early, but so far, he looks every bit like the “franchise QB” that Will Muschamp has been searching for. Deebo Samuel is the most dangerous weapon in the SEC right now, and he’s going to be a matchup nightmare on a weekly basis. And defensively, that’s saying a lot that South Carolina only allowed 13 points at Missouri.

I’m higher on the Gamecocks than some others because they already beat two Power 5 teams. South Carolina and Louisville are the only teams that can improve to 3-0 with three wins vs. Power 5 teams. If that happens, the Gamecocks need to be in the SEC East title conversation until further notice.

Jon Cooper, director of operations: Although a strong case for South Carolina can be made, I’m going with QB Jake Fromm and Georgia. Fromm just feels like the guy for the future, regardless of if/when Jacob Eason returns.

Although he’s young, Fromm makes the offense move and he is poised while doing so. I do think Eason could win a lot of games this year, but the fact of the matter is Fromm led the Bulldogs into South Bend and upset Notre Dame.

While Georgia sitting at 2-0 isn’t that big of a surprise, the QB who is leading the team is. And he looks good doing it. It’s tough coming from high school to college at a big-time program and playing immediately, but Fromm will make it look easy this year. Yeah, there will be some growing pains, but he’s one of the biggest surprises so far in the young season.

The beautiful thing for Fromm is he has a big-time backfield and loads of talent on defense. He doesn’t have to win games by himself.

Clint Lamb, Alabama, SEC West reporter: Mississippi State has to be on that list. The schedule hasn’t been difficult, but that doesn’t mean they haven’t been impressive — especially defensively.

Everyone knows about Nick Fitzgerald, but it was actually the defense/special teams that shifted the momentum against Louisiana Tech following a blocked punt by DT Jeffery Simmons. They were down 9-0, and Fitzgerald wasn’t playing well at all.

Overall, State’s defense is on pace for 32.5 sacks this season — a significant improvement from last year’s 25 sacks, which finished tied for 8th in the conference. In addition, the Bulldogs have the top-ranked pass defense in the SEC, giving up only 89 yards per game.

Good teams find balance, and that’s exactly what Mississippi State has done so far. There might not be a more important player to his team’s success than Fitzgerald, but the rest of the team is proving that he doesn’t have to do it all on his own.

This weekend will be a tough test against LSU, but it’s hard not to be impressed by a defense that lost 76 percent of its sack production and 57.1 percent of its interception production from last season, and is still finding a way to be even more productive.

Luke Glusco, copy editor: I know I’m not going way out on a limb here, but I’m pleasantly surprised by the level of efficiency LSU is showing.

There were certainly enough offseason changes and questions to think the Tigers might show some rough edges early in the season.

Instead, they’ve been solid and steady since the opening gun. No Arden Key, no problem. Is Danny Etling the QB? You bet your Cajun butt he is. Will Matt Canada’s offense run smoothly from the start? So far, so good.

The team has zero turnovers. Etling is hitting on 70 percent of his pass attempts, including some deep balls, directing the show as a high-level game-manager. Derrius Guice is getting his work, but not too much. Averaging 21 carries for 112 yards through two games, he’s staying fresh while gaining momentum.

Key’s return will make the defense even better, and I doubt we’re anywhere near the top of what Canada can dial up. I didn’t expect it to go quite so perfectly for Coach O out of the gate. He’s a likable guy — hope I haven’t jinxed him!

Chris Wright, executive editor: Ole Miss. We thought the offense would be fun to watch — 4th-and-30 at your own 5, go for it, who cares? — but it’s wildly exceeded my expectations.

It’s far from a sure bet that what Shea Patterson is doing now will ever work on Sundays, but The Shea Show has quickly become must-see TV on Saturdays.

His receivers certainly watched and learned from Laquon Treadwell on what it means to be a physical beast on the outside. In the run game and passing game. There won’t be many 50-50 balls that this group won’t win.

Physically, they all look like they belong in the NFL now, and most of them have another year with Patterson before the NFL comes calling.

Bump-and-run these guys and it’ll result in bumped-and-run over.

Nick Saban hasn’t slowed down this offense in three years. I don’t think that magically changes Sept. 30 in Tuscaloosa, either. This is the most dangerous offense in the SEC, one fully capable of creating chaos in the race to Atlanta.
