Gronk's Inury List

After listening to Rob Gronkowski, it's easy to see why he retired so soon from the NFL. He admitted to nine surgeries during his career, as well as over twenty concussions. He blacked-out during at least five of them.

His body was just done with football. He cited the mentally draining aspect of trying to come back from all of his medical situations.

Selfish fans want him to keep playing, but they should be happy for him. He knew when it was time to walk away.
