Nobody was expecting him to be ready for the first week of the season anyway. If he is able to get on the field next week, it still would be a surprise. He is putting in work though and might be able to pull it off.
I am looking for him to get back onto the football field in week 3 and making an impact. GRONK SPIKES for everyone.
He might as well rest for a couple of weeks and ensure that he can last for the rest of the season. He will be needed more at the end than at the beginning.
