Pretty ridiculous to insinuate that it's anyone's fault (Manny or the kids) and making assumptions that people aren't "doing the right things" off the field.
Say what you want about this virus, but one thing that there is no debate about it how insanely contagious it is. There's simply no way to completely guarantee you keep it out of your building long-term. However, if there's a ton of actual positives, that's disheartening, because if you're socially distancing and following all guidance, there shouldn't be rampant transmission. But if you just had a couple kids actually test positive and everyone else is being quarantined out of caution, that's probably the best you can hope for. Guys in the NFL are getting it, and it's literally their job to NOT get it. Kind of hard to point fingers at kids or a coach if you have a positive test here or there.
Cool thing is nobody will ever really know what the situation is, because Miami guards this kind of information like it's data from Area 51.
