Lets look at the positive of this situation.
Best case scenario, KC makes it to the Superbowl and then FINALLY has surgery to repair the haglunds deformity. It should only sideline him 6-8 months. However if you take into account previous injuries KC has had to deal with. I wouldn't be surprised if he misses more time next year.
So we'd be 3 years into a contract with him playing what, 2 full games maybe?
Just want to let it be known, I'm not really blaming Berry. Just the entire situation seems fitting as a Chiefs fan.
