Bill Belichick might know something we don't know on the Rob Gronkowksi front.

The New England Patriots head coach joked that his phone was going to "blow up" around 9:00 a.m. Tuesday, when Gronk will make some unspecified "big announcement" on his Instagram page that many are guessing is his return to football.

Gronkowski retired after the Patriots prevailed against Jared Goff and the Rams in the Super Bowl. Among his many post-football ventures are a partnership with a water bottle company and a stint as an analyst with FOX, where his unique, magnanimous personality has shone through and garnered rave reviews.

Of course, he could go back to racking up 100-yard games with the Patriots...

Be warned, Patriots fans. Gronk's "big announcement" is almost assuredly going to be the unveiling of some business deal. However, Gronk un-retiring and joining back up with the Patriots would probably be one of the more predictable things to happen so far this season.
