I don’t think anyone should be suggesting that he isn’t *really* retired. That’s silly. What many are pointing out is that his agent would basically have him sign another paper, which means that he can pretty much come back at any time, assuming that it’s before the end of October.
In other words, he’s officially retired, but as we’ve seen in the past with tons of retired players, he reserves the right to change his mind at any point and the process to return is simple. For the record, I think he remains retired for the 2019 season and allows his body to heal, but I wouldn’t be surprised to hear the same chatter again next summer.
