Thanks for giving us everything everyday and I wish nothing but the best my man. https://t.co/3XMbmf1XxcThe reaction everyone was waiting for soon arrived from his long-term teammate and friend, Tom Brady, who released the following statement:"Teammate, friend, brother, just a few of the words that come to mind when I think of Gronk. Nobody has ever embodied the idea of ‘leaving it all out on the field’ like Rob has throughout his entire career. Every single snap, I knew that no matter how many people you put in front of him, he was going to get to his spot."

Having Gronk in your locker room was every NFL player’s dream. I’m proud of all that we’ve accomplished together, and even more excited for all you have ahead of you. Congrats Gronk, you deserve it.”Not Rob Gronkowski's first attempt at retirementThe former Patriots and Buccaneers tight end previously called it a day in 2019, following the Patriots' victory over the Los Angeles Rams in Super Bowl LIII, and at the time he had this to say:"I was not in a good place. Football was bringing me down, and I didn't like it. I was losing that joy in life... I could play right now if I wanted to play. I'm feeling good. Physically, I could do it. Mentally-wise, desire-wise, it's not there... I am very satisfied with where I am in life right now."He would later reverse that decision a little over 12 months later and rejoin Brady, who had just arrived in Tampa Bay. They quickly rediscovered their old magic as the Bucs made it to Super Bowl LV, where they dismantled the Kansas City Chiefs 31-9, with Gronk and Brady connecting for two touchdowns.Rob Gronkowski has now decided that he is done for a second time, and will retire safe in the knowledge that he will be entering Canton, five years from now.If you use any of the above quotes, please credit PFT Live and H/T Sportskeeda.
