Salary cap space has yet to win a Superbowl. I don't know why so many fans fetishize it. Cap space is not a replacement for good good players and it doesn't directly lead to good players. It just sounds cool in theory and but it's nothing to get excited over.
It's always interesting for me to witness people being stingy about money that isn't theirs. It's right up there w/ listening to a person spend "if I won the lottery" money.
