Eh...until yesterday I thought he was coming back, not this year as I am stating since his retirement, it wouldn't make sense for him to come back at the end of this season, he needed one full season off (that would result in 18 months out of football) either from a health standpoint and also financially, I think he could sign a 2 year - 20/22 Mi contract next season, he would make more than he was doing and with his body fully recovered.
Now, I'm revisiting this idea, I thought yesterday he was exaggerating a bit saying he couldn't sleep for weeks after the SB etc due to that tight injury. I'm not saying it wasn't a tough one, at the time he took that hit I knew that was a bad one, it just didn't hit right and he was in full speed. But no one can stay weeks sleeping only a few minutes every night. Now brain is another story.
Also, this campaign, he's probably making millions, pharmaceutic industry is a billionaire industry, he is the right "player" in the right spot to drive this campaign, he's certainly aware of that and capitalizing on it.
