Bit of everything. Injury crisis years aren't uncommon, 2018 springs to mind, but as well as that there's also the Covid stuff.Cant remember a time when team GB was this thinned out. Have they just been incredibly lucky with injuries or is this far less depth than normal?
In England, where most GB athletes live, after the first couple of months the very top athletes were able to train even when there were later lockdowns and local restrictions. Whereas the exemptions in the rules didn't cover people who weren't already at the top of their game. I forget the exact wording, but it meant athletes who'd have turned senior this quad faced many more limits on their training than those already in national squads. So it's not a surprise that it's been a weak couple of years for new seniors breaking through. Also some clubs have gone to pot.
But also, this is just how a lot of teams look now. Every minor WAG team medal this quad has been won by a team who rely heavily on their superstar. That's been a more successful cohort than the teams who are more balanced like Japan. The talk is about GB because the others still have theirs available, but GB are better off than Canada or France would be in this situation and probably no worse than Brazil. A team of Kinsella, Achampong, GMF, Evans and Downie could break 163 without anyone doing anything remarkable.
