Take it for what it's worth, which is probably nothing.
Yeah I wouldn't read too much into this.
He probably just wants to take some time. Maybe he even has a date in mind, like after the new year, or after the holidays or something.
He probably didn't want to take a full practice or get in their way, but he wanted to support the team like he's been doing in the room after games. Then felt like he wanted to do a little more than just stand at the bench, so he decided to stickhandle a few pucks.
Obviously this situation is concerning, but we still don't have any evidence to suggest he isn't just being extra careful. We heard he got a bit worried about his long term health and career last year when he was battling that concussion. Then he got another one this year.
This might just be all Bo's idea to take this extra time off to give his brain plenty of time to heal. They've basically left it up to him it sounds like. It's still possible this could just be some early career health adversity that he can overcome and have a long productive career.
We really don't see many guys who establish themselves as proven NHLers have their career ended by concussions. Knock on wood that doesn't happen with Bo, but mostly it's guys like Hishon who never really established themselves as NHLers. IMO because their confidence was rattled to the point where they doubted themselves too much, or played a bit timid.
That likely won't be Bo's problem, and it wasn't the first game back he played. He looked like his usual confident self. Which is a good sign, especially considering he was willing to be cautious about his health, but still played with confidence on the ice.
