Who knows why he couldn't make it, or if he just didn't want to go. Honestly if I were getting a Superbowl ring and have a chance to see some of the guys I won it with, it would be hard to miss that celebration. But it is what it is the Hawks cannot keep every good player and every good player dosent want to stay. K9 obviously felt like he was more important than he was given credit for. I love K9 but I dont see him staying healthy all year as the number one back. But I think if he wanted to show he was the bigger player, than maybe not go to a team that has Mahomes. He should do well with KC because that team will be in the conversation of Superbowl contenders with or without K9.
