Breaking: Trent Williams Suspended 4 Games

[FrenchSkin]

I have two questions:

1) When a player misses a test, why isn't the NFL forcing him to take another one?

I'm just surprised with how easy it seems "-hell I'm full of illegal substances I just won't go -Oh daaamn he didn't come, what are we gonna do?! There is absolutely no way we could say something like "you either take this test tomorrow morning or are suspended for the rest of the season"..."

2) Everyone seems to be 100% sure it was pot... how do we know that for sure? (not a rhetorical question, real one)
