Rob Gronkowski, the best TE of the last decade, has announced via social media his retirement.
Almost unguardable by anyone he was the ultimate matchup nightmare. Better blocker than people thought too.
Gonna just take his $$$, invest some and have plenty of fun, some of which his NFL obligations kept him from fully engaging in.
Probably a HOFer but the relatively short, injury-plagued career could make it an interesting conversation...
