Thing is has Covid really changed who has qualified in any real way?
Who has benefitted?
Pool A:
Montpellier 5 points to Montpellier, but 9th still, so probably going to miss out anyway.
Bath & La Rochelle - 2 points but both still where they would roughly be.
Sale & Clermont - 2 points Could maybe argue that this has pushed Sale just that bit higher, but only be with Montpellier who are another beneficiary.
Racing - 5 points may put Racing higher than they would have been, but Racing win was still the likely outcome.
Pool B:
Bristol - 7 points possibly the team to benefit the most based on form you could argue that had Scarlets won this game it could have given them momentum and a draw basically meant they were likely of qualification. However they beat Stade to back it up so...
Bordeaux - 2 points. Still qualified regardless and probably would have won
Scarlets - 2 points. Their only points. Could things have been different if they could have played the first match, definitely one of the biggest losers from the cancelled games.
Toulouse & Wasps - 2 points. With Wasps winning the week after this is probably the biggest potential upset, but I still think Toulouse will scrape through.
Stade Francais - 2 points their only 2 points so not benefitted.
Leicester - 4 points, only really guaranteed a top 2 finish.
Cardiff - 5 points - Again like Scarlets a bit of what could have been had they been able to field a full strength team. Definitely helped them to qualify if they do, but hard to begrudge them after the opening rounds as Teddington mentioned above.
Overall I don't see any team except Bristol benefitting hugely and unless Toulouse do miss out, no huge upsets.
