Perfect records in reserve and youth football during a summer window are almost always a mirage. Orlando City II and the Icelandic U19 sides sitting at 100% look compelling on the surface, but these are developmental squads playing in low-stakes environments where defensive shape is deprioritised by design — coaches are developing attackers, not grinding clean sheets. Eight matches is nowhere near enough to treat that hit rate as a stable signal, especially mid-preseason when rotations are heavy and fitness levels uneven across squads.
The 75% page-wide average is genuinely elevated, but that's partly structural — preseason football across the board skews open. The sharper angle here is filtering for senior fixtures with samples above 12 matches rather than chasing the headline 100% names. Youth and reserve tier data this time of year flatters the market; it shouldn't be driving your staking decisions.
