Good, the bubble should only be used for lightning when players are in danger, not just to keep the players (and coaches) dry. No point running inside to avoid rain, when you're likely to have to play in it when the season starts.
Which was the intent of the Bubble in the beginning anyway. People forget that we lost numerous practices Saban's first year here because of dangerous weather, not rain, but severe storms and lightning. That's why he had it built. I never understood the hatred of the Bubble. Coaches have misused it, but it is a VITAL tool for our team due to Florida's weather. Use it for safety.
