So, then, you're saying it was the weather. Got it.
If I'm allergic to pollen, and I've walked through a hallway a dozen times and had no allergic reaction, and then someone puts a bunch of pollen-filled plants in there, and I walk through it and sneeze, and my eyes get all itchy ... when someone asks me why I'm reacting like that, I say "it's the pollen" not "it's my failure to prepare for the pollen."
Maybe one day you'll be walking down the street and someone comes up to you, tells you they're going to punch you right in the face, and they do so. And when you come to, and want to press charges, the cops will laugh and say "his punch didn't knock you out ... it was your failure to defend against his punch that knocked you out."
Again, these guys have had ZERO issue with ball security this year. Prior to this they've been in plenty of situations (heavy traffic, getting whalloped, hit from behind, etc.) where you need to protect the ball more than normal and they ... didn't fumble. Suddenly, one game, with rain ... and the ball's popping out like popcorn. But it wasn't the weather.
