Your post above was prior to the Dallas game. At the time the Saints were riding a 3 game winning streak dating back to last year.
With that said, I'm assuming you mean during a singular season. Considering at the time of your post the Saints were on a 1 game winning streak in 2024.
Now, after the win against the Cowgurls, the Saints are on a 2 game winning streak in the current season.
This leads to this. The Saints best chance to go on a 3 game in season winning streak is in week 3, this Sunday.
To your point, if it doesn't happen in week 3, the best chance for it to happen comes again between weeks 6-9 and again weeks 14-18.
Why wait. Get on with it now. Saints beat the Iggles and soar to new heights. Who Dat!
