Gronkowski caught five passes for 72 yards and an incredible three touchdowns in the contest, easily the rookie's best performance in nine career games. It was a bounceback game, as well, as Gronkowski had a costly goal-line fumble the week before as the Patriots were upset by the Browns.
"It definitely feels good," he said after the game. "It's just opportunities. When you get opportunities, you've got to step up. Obviously, last week didn't go the way we all wanted."
Gronkowski's previous best day as a pro came in Week 3, when he caught three passes for 43 yards and a touchdown, but until his breakout against the Steelers Gronkowski had only made a minor impact in his first NFL season as a risky second-round pick.
No one has ever doubted Gronkowski's pure skill -- he was considered possibly the most complete tight end in the 2010 draft, with a combination of strength and speed and strong route-running skills. But the Arizona product missed the entire 2009 season after having surgery on his back to fix a herniated disk and repair nerve damage, and it was unsure how he'd recover.
Judging by Sunday's performance, I think it's safe to say he's fully recovered.
