"Should have kept Courtney Lee."
I'm sorry. I know nobody likes the grammar police, but this one is becoming a pet peeve of mine. I realize that should've said quickly can sound like should of, but it's clearly incorrect usage, and shows that the person using it is being fooled by the sound of the contraction for "should have."
That's all. Again, sorry, but I hope some people take note of this and learn to correct this small grammar mistake. I don't mean to criticize; I'm just trying to give some friendly advice.
