If KC were to resign their current core group in about 3 years they would have an old, overpaid, under performing team and no money to sign anyone to make it better. In most cases, signing your own guys to long term extensions only fulfills emotional goals and isn't in the best interest of the success of the team. Imagine if we resigned Prince. That would have really set the franchise back. Losing your players at about 30 years old by trade or free agency is often a blessing in disguise.
