Knights actually have an okay chance of making the 8 now.
Eels have a tough run home and likely won't make it, Souths to take their spot. Sharks are probably finished. Leaving 1 spot for Knights/Manly/Roosters. Knights have a 1 point advantage over Roosters and a huge F/A advantage over Manly.
Relevant run home:
Sharks [26] - Panthers (A), Souths (A), Titans (H), Cowboys (A), Knights (A), Raiders (H)
Eels [24] - Storm (A), Dragons (H), Broncos (A), Roosters (H), Panthers (A), Bye
Souths [24] - Tigers (A), Sharks (H), Dragons (H), Knights (A), Bye, Roosters (H)
Knights [23] - Raiders (A), Dolphins (A), Dogs (H), Souths (H), Sharks (H), Dragons (A)
Manly [23] - Dragons (A), Roosters (A), Panthers (H), Warriors (A), Dogs (A), Tigers (H)
Roosters [22] - Broncos (A), Manly (H), Dolphins (H), Eels (A), Tigers (H), Souths (A)
Predicted points (aka completely guessing)
Sharks; 4 - 6 points
Eels; 4 - 6 points
Souths; 10 - 12 points. Easiest run home of the lot
Knights; 6 - 8 points
Manly; 6 - 8 points
Roosters; 6 - 8 points
Will be a lot tighter around that 7th - 8th position than expected. I didn't check the Cowboys but they might be fighting it out for the bottom 2 spots as well.
