For cup I'd predict a HumanFund vs Flashover final. Those two will be a good matchup, might come down to GS and whether G's recent purchases can get into good GS by then
I think there are some other really interesting seeding battles to end the season too. Mainly the 3-5 spots in the Great 8 and 3-6 in the Big 8.
After being in a relegation fight all season, I think Silverbacks might be the favorite to snag the 3rd seed. 3 of their final 4 games are at home and the only road game is against the 8th seed. Beware and Visionaries both only have 2 home games left and Visionaries is still dealing with their rough injury luck
On the Big 8 side, it looks like Fury is likely to grab a top 4 spot but not settled yet. Based on remaining schedule and current PD, I'd guess it finishes as Fury 3, 10inch 4, Human Fund 5, Big Gulp 6. If all of my predictions are right, Flashover and Human Fund would be a rare cup final matchup that is also a relegation matchup!
