If you play for the New England Patriots, you better bring your A-game.

For almost 20 years, a Patriots loss seemed like an anomaly. Their six Super Bowls between 2001 and 2018 set an unprecedented mark that may never be achieved again.

But with such a dynasty comes high expectations, and that's why Rob Gronkowski absolutely hated losing.

Gronk won three Super Bowls with New England and never missed the playoffs, but the regular season was a grueling process for the four-time first-team All-Pro tight end.

Even the victories were hard to enjoy, he says.
