The bubble is my least favorite play in football
When executed with great athletes and good blocks, it's a dynamic play.
Unfortunately when it goes wrong, it's a loss or very short gain and you're now in 2nd and 3rd and long. Which is the last thing that lesser athletic team can afford.
Like any play, it has positives and negatives. Just can't run it as your base offense or against vastly superior teams and expect success.
