Let’s assume the Los Angeles Rams needed a little bit of time in the regular-season opener to settle in. Most of their starters didn’t play in the preseason. Let’s say it took a half of action to get into the flow.

Well, since halftime of Week 1, the Rams have outscored their opponents 57-0.

The Rams’ opposition hasn’t been great, but on both sides of the ball they look like the best team in football. And they take the No. 1 spot in the Power Rankings this week.

Maybe we can finally put away the nonsense that adding a lot of good players in the offseason is a negative. As I said in the Rams’ preview this summer, just because Vince Young said “dream team” a few years ago and that Eagles team wasn’t good doesn’t mean every team that “wins the offseason” is doomed. The 1994 San Francisco 49ers crushed the offseason, and they won a Super Bowl. The Denver Broncos built the core of a Super Bowl 50 champion through free agency. Every championship team since the start of free agency had at least one significant player who was acquired via free agency. And so forth.

The Rams attacked the offseason like a team that had a one-year window to win a championship. That’s not the worst approach in the temporary world of the NFL. Remember, two years ago it looked like the Oakland Raiders were building a long-term contender. You can’t wait for the slow boil, because the NFL changes so fast. The Rams’ plan was just fine, and it seems to be working.

The Rams’ defense, which added cornerbacks Marcus Peters and Aqib Talib and also tackle Ndamukong Suh, hasn’t given up a touchdown in seven quarters and no points at all in six quarters. The offense, with new playmaker Brandin Cooks, is tied for fourth in the NFL at 6.3 yards per play, and it still doesn’t seem like we’ve seen their best. The Raiders and Cardinals, the Rams’ first two opponents, are bad. But it’s tough to dominate any team in the NFL. Aside from the first half at Oakland, the Rams have dominated in every way possible this season.

We’ll see in upcoming weeks if the Rams really are the best team in football. They have back-to-back games against the Chargers and Vikings, then set off on a three-game trip. The competition will get a lot tougher. But at this point, there’s no reason to believe the Rams can’t handle it. They look like a powerhouse. Maybe all teams should sit their starters through the preseason.

Here are the power rankings after Week 2 of the NFL season:

32. Buffalo Bills (0-2, Last week: 32)

If we’re being positive about the Bills, and not talking about Vontae Davis retiring at halftime, they outscored the Chargers 14-3 in the second half and made it a respectable game for a while. That doesn’t mean the Bills are marching into Minnesota this weekend and pulling off an upset, but it was nice to see some signs of life after being outscored 75-6 to start this season.

31. Arizona Cardinals (0-2, LW: 30)

It’s early — really, really early — but I’m starting to wonder about Steve Wilks. The Cardinals weren’t close to this bad last season, and that was without David Johnson. They were 3-4 in Carson Palmer’s starts, so you can’t blame his retirement. This team is entirely lost, and Wilks said he never considered benching Sam Bradford for rookie Josh Rosen in a 34-0 loss on Sunday. Wow. Let’s say it’s way too soon to judge Wilks, but there are already warning signs.

30. Cleveland Browns (0-1-1, LW: 31)

I’ll give Tyrod Taylor credit for driving his team downfield, twice, late in Sunday’s game. But where was that for the first 55 or so minutes? Everything Taylor threw Sunday was short, until he had to air it out. If the Browns are going to play an extremely conservative dink-and-dunk offense, just start rookie Baker Mayfield (which they should be doing anyway).
