Some of us rooted for Hayward for 7 years and are still stuck in the "terrible fan" mindset of actually rooting for the guy. No not all season-ending injuries are the same. That had a specific brutality and shock factor to it that definitely leaves you a little more uneasy and unsure about the future for somebody who has succeeded so much. Obviously there's a lot more to say about this injury than X's so that comparison is a little off the mark.
Just cause he was in another jersey doesn't make anybody a "bad fan" for being very upset at what has happened to him. And no you're not a "bad fan" for not caring. You just got over rooting for him and accepted the bridge is burned. Some of us haven't and still want him to succeed, even in another jersey. It's ok.
