You play a team each week with the same record as you. That way, there's only a handful of teams left at the end of the season undefeated. Also, each week (in theory) should be competitive because the undefeated teams are playing other undefeated teams, not teams that have lost a few games and are down the bottom of the standings.
This is reflected by what you're saying as you haven't lost yet this season, compared to last season where you lost your second game.
As you're winning again now, you will get another stronger opponent at the same level as you in the standings next week.
