Rob Gronkowski got the fans before, and NFL followers aren't so sure he won't just get them again, after his recent retirement announcement. This is his second such announcement in the last three years, mind you - from the Tampa Bay Buccaneers.The last time 'Gronk' called it quits, his sabbatical lasted a season. He was back catching passes from Tom Brady, not in New England, but wearing brand new digs in West Florida during the 2020 COVID-stricken season.This time around, fans are feeling a 'boy who cried wolf' vibe from the announcement. One NFL fan compared Gronkowski's indecision to rock band KISS' retirement announcements:Joe@jspinato8@AdamSchefter Don’t be surprised when people stop caring about players saying they’re retired. These guys are as bad as Kiss on their 15th farewell tour.6@AdamSchefter Don’t be surprised when people stop caring about players saying they’re retired.

Sick of these guys retiring 20 times.Tom Brady's retirement message to Rob GronkowskiThe friendship between Tom Brady and Rob Gronkowski was enshrined in NFL history with their three Super Bowl titles together, during 2015-2019 with the Patriots, but it was immortalized with their shared title in Tampa.Brady shared a heartfelt message for his good friend and longtime QB-TE other half:"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 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. Even more important is the person he was on and off the field. Focused when he had to be, and FUN the rest of the time. "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 in front of you. Congrats Gronk, you deserve it."Considering 'Gronk' was just writing a similar message to Brady two months ago, fans have every right to be skeptical about what the future holds for the 11-season NFL veteran.
