Shoulder issues are always a big thing but we shouldnt automatically assume this is something more than just regular ST soreness. Im glad we are being careful with him.
If you want to be an optimist, you could say they're related. According to Soroka, this one is the result of working out his shoulder too hard in January. The workouts being in response to his shoulder injury last year. So without the first shoulder injury, this soreness might not have happened.
If you want to be even more optimistic, it's entirely possible that we wouldn't have heard a thing about this injury had he not missed half the year last year with a shoulder injury. It's not that uncommon for guys to experience soreness in camp that sets them back a bit but isn't really a problem.
However, while I want to believe this is just some muscle inflammation and nothing to be worried about, I can't shake the feeling that there's a bigger problem lurking.
