I don't know if this is on purpose....
On first round in matches when ready-go, actually you can move before the camera gets down to the players (and before the "GO").
I thought this can be on purpose on "Last stand" to runaway and see what's happening/seek your pal/weapons or get a FREE random dropkick 😤
But in sport modes this can be so confusing. Most players just stay still drooling while somebody takes de ball away 🤣
Anyways, its strange that only happens in first round.
