I've heard the phrase 'mathematically possible', this must be what it means (!)
2 spots up for grabs
Panthers [26]...play Tigers (H), Titans (A), Manly (H) - even if they lose all 3, won't be an 84 turnaround in F/A so we can't catch them
Titans [25]...play Knights (A), Panthers (H), Cowboys (A) - even if they only get one win we can't catch them, they next play Knights, so...😱
Therefore, unless Knights spring the big upset, we're kaput
However if Knights can do it...
Warriors [24]...play Cowboys (A),Tigers (H), Eels (H) - we need them to lose 2 of these, plus we'd need to make up 19 in F/A
Tigers [24]...play Panthers (A), Warriors (A), Raiders (A) - we need them to lose 2 of these, and we need to maintain our 3 point F/A advantage over them
St George [22]...play Roosters (A), Eels (A), Knights (H) - terrible F/A, they will lose at least one so they aren't a threat
Manly [20]...play Storm (H), Raiders (H), Penrith (A), must win all 3.
Simple! 😉
