I don't disagree with your broader point, but I think in the team sprint, you can still lose if your lead-off and second line riders aren't strong enough - even if you have the best individual sprinter on your final leg.
I criticise others for sharing opinions that are little more than their hopes and wishes without them being backed up by data so I'll try and put my point across looking at the 2023 Worlds, the 2024 Europeans and Hong Kong Nations Cup - the last 3 occasions where the teams went head-to-head.
Opening Lap:
Cyclist
'23 Worlds
'24 Euros
'24 HK NC
Pauline Grabosch
18.945
18.650
18.935
Lauren Bell
19.036
Katy Marchant
18.750
18.763
From this small sample, whoever wins the opening lap goes on to take the title - it's not definitive but it's an important trend. One of the reasons I think Marchant gets the nod over Bell is her consistency - putting down 3 rides under 19 seconds - and in particular hitting 18.7 in the final
Second Line Rider:
Cyclist
'23 Worlds
'24 Euros
'24 HK NC
Emma Hinze
13.289
13.455
13.485
Sophie Capewell
13.394
13.725
13.815
Going through the data, I can't find an instance where Capewell is faster than Hinze- not saying it hasn't happened, I just can't find it in the data files I have. The question then becomes how close can Capewell go to Hinze. If she can keep it within a couple of tenths of a second, then she will put the team in a strong position. If it strays out towards half a second, then it becomes unlikely that GB will come out on top.
Third Line Rider:
Cyclist
'23 Worlds
'24 Euros
'24 HK NC
Lea Friedrich
13.614
13.794
13.929
Emma Finucane
13.493
13.676
13.514
The stat shows Finucane's progress over the last year - she's now consistently the fastest of the 3rd line riders. If she takes over in the lead, I don't see Friedrich being able to catch her. If she takes over 0.1 - 0.2 seconds behind, I think GB would be marginal favourites but any deficit beyond 0.2 becomes more difficult to predict.
So, based on this, I would argue that the team sprint gold will be won or lost with the second-line rider. Great though Finucane is, she needs to be in touch when she takes over -she doesn't need to be ahead, but she needs to be close.
