You elevate what he did within the context of what few others have done for the Patriots.
Malcolm Mitchell caught 6 passes for 70 yards in Super Bowl 51. Just looking at receiving stats over 53 Super Bowls, that performance is simply "ok."
But once you factor in that he's still the only rookie WR to catch a pass from Tom Brady in what is now 9 Super Bowls, the trust Tom showed in him in the 4th quarter with the game on the line, I don't know how you can think of his performance as anything but excellent.
Considering the Pats history with WRs, Gordon's lack of games played for almost half a decade and his hammy, yes I think his season was close to excellent. At the very least, it was much better than just ok. If he doesn't improve this year, it's all on him.
