it was very predictable though. After the surgery they said he'd be re-evaluated in 4 months. That's the 1st week in March. So then, if it's a positive evaluation they'd clear him for some BB activity but it would still probably take 3 weeks, or more before he'd be ready. And a shoulder injury is more prone to re-injury than most other injuries. Maybe the best case is Zach starts playing again with 2-3 weeks left in the season. But it could be later
I'm guessing he'll be back sometime in mid-late March, but any little setback, like Nurkic had, could end the season for him
