How EA is keeping Super Bowl Legends a secret and why is it causing so many glitches?

EA has surprisingly been able to keep their daily Super Bowl legends a secret until the very moment of releasing them. Usually, players are leaked prior to their release and rumors swirl around the different grapevines, but during the current event EA has been holding their cards close.
This then begs the question: Why?
Well, EA might be getting fed up with the constant leaks from people who are able to see the code during the testing fase. They want releases to be surprises, by forgoing the testing fase.
But unfortunately without testing, there's an increased risk of glitches occurring. That's what we've been seeing during the week, with constant glitches. So is this now the way for EA to continue? Can we expect more glitches to occur? It all depends on EAs next move. We'll have to wait and see what happens after the Super Bowl promotion.
