While it looks ​like the ​New England Patriots will head into the 2019 season without future Hall of Fame tight end Rob Gronkowksi, ​New York Jets safety ​Jamal Adams isn't convinced that Gronk is done with football.

The Jets star safety is questioning the 29-year-old's decision to hang up his cleats, and Adams thinks that No. 87 will be back in a Patriots uniform sooner rather than later. 

​​"He'll be back," he told reporters in New York at the Jets' uniform unveiling on Thursday. "He'll be back. He ain't fooling me." 

It's a shame that we only got to see Gronkowski and Adams duel for two seasons, but whenever they matched up, it was an intense, hard-fought battle. Part of the Jets' decision to take at Adams with the No. 6 overall pick was his ability to handle tight ends in man coverage. While Gronk got the better of him as a rookie, Adams made some improvements last season and held his own.

The 23-year-old delivered a massive hit on Gronkowski in a matchup this season, as the tight end was clearly shaken up after the play. 

While Adams, ever the competitor, wants one more shot at Gronk for old time's sake, it seems unlikely he makes a return to the football field. Should he ever decide to come out of retirement, Gronk should know that Adams will be waiting.
