#4 Rob Gronkowski
After the New England Patriots' Superbowl loss at the hands of the mighty Philadelphia Eagles, star tight end Rob Gronkowski stated that he was considering retirement from the NFL.
This immediately led to a number of dirt sheets suggesting that WWE would be interested in signing Gronkowski if the 28-year-old decided to hang up his cleats.
Two months after the Superbowl, it appears that Gronkowski will return to the Patriots for the 2018-19 season and will not pursue a career in professional wrestling at any point in the near future. However, that doesn't preclude him from making another one-shot appearance at WrestleMania.
Gronkowski recently had a jocular exchange with Jinder Mahal on Twitter. Perhaps he could interfere in the United States Championship match and foil the Modern Day Maharaja one more time.
