In each of the past two seasons, Toronto FC was the clear and obvious frontrunner in Major League Soccer.

That might feel a bit like 20/20 hindsight about the 2016 team that won neither the Supporters' Shield nor MLS Cup, burdened as it was by playoff failures past. Each of that year's New York sides was flawed in its own way, Mauro Diaz's knee injury blew open the Western Conference and no team had anybody like Sebastian Giovinco. But last season's Toronto was a destroyer of worlds, the first club in MLS history ever to win a domestic cup, the Supporters' Shield and MLS Cup in the same calendar year.

The point is that Toronto has for a while now been the default answer when any rational fan is asked who was likeliest to lift silverware in the end.

That is no longer the case. And the team that has picked up that mantle looks primed and ready to run TFC off the field on Saturday afternoon at Mercedes-Benz Stadium. Atlanta vs. Toronto (4:00 p.m. ET, ESPN) feels significant both as a marker of the changing of the guard and of shifting eras.

To clarify: I'm not writing off the Reds entirely. Two straight victories have them heading into the weekend six points out of an Eastern Conference playoff spot, a formidable but not impossible hill to climb. With this team's pedigree, and the amount of talent still packed into the roster, it wouldn't be shocking if Toronto not only surged into the postseason but made some serious noise once there.

The team TFC faced in each of the past two Cup finals has mastered this kind of trajectory. Seattle is at it again, unbeaten in six following a dreadful spring and early summer, suddenly right in the thick of the hunt as if the first four months never happened.

That's part of the reason, however, why league observers outside of the Pacific Northwest are likely to remember this recent era as belonging to Toronto, not Seattle, even if the two clubs ended up with a championship apiece.

Standalone silverware is enough to appease your fan base, but in order to stand out in league history, the regular season does matter. Start-to-finish dominance does matter.
