Emma stone took The career Lindsay could of had.

Think about it, similar age, similar look, teen film success, both can sing, both kinda pretty in a girl next door way.
Only difference is that Lindsay screwed herself bad with drugs and plastic surgery and now looks like the poor poor poor mans version of her once self.
Step in Emma, clean, healthy and more pure lifestyle is now the acclaimed actress Lindsay could have been.
It's no coincidence that once Lindsay career started to go downhill, Emma's took off.
If Lindsay never turned into the party girl, she would have had all those films that went to Emma.
