If you follow anything about James Harrison during the offseason, you know he's a workout warrior; whether he's bench pressing over 400 lbs. or running wind sprints with a weighted vest in extreme Arizona summer heat, James Harrison has people seeing him as the most terrifying of Steelers' defenders, even at age 37.
Harrison has not been devoid of criticism in his old age, even unfounded poorly contrived suggestions to delegitimze his own accomplishments.
A recent Instagram user flaunting Patriots hash tags accused Harrison of using anabolic steroids to make him more effective of an athlete. Harrison had an appropriate response:
James Harrison has been the recipient of several fines and even a suspension in his career for being an aggressive defensemen for the Steelers and hitting players "too hard."
In 2010, Harrison accused the NFL of targeting him specifically as a player for excessive fines in order to limit his success in a time when the Steelers' defense was dominant and on it's path to a second Super Bowl appearance in three seasons. Whether Harrison was correct or is a debate for another day, but it wouldn't be inaccurate to say that Harrison was under close watch of the NFL for multiple years of his prime.
Had Harrison been a steroid user, he most likely would have been caught by now along with the several other NFL players who have been suspended for performance enhancing drugs.
Silverback's response was appropriate, he's working so hard that other Steelers are trying to challenge him with their own impressive feats in workout routines. His work ethic speaks for itself, the squabbling of a Patriots fan just shows that others are noticing his efforts and are scared enough of what he might be in 2015 to the point that they hope for his strength to be attributed to drugs and not his own merit. A simple thanks for the subconscious admiration from a detractor was a perfect response.
And the dig at the audacity for a Patriots fan to fabricate the idea that someone might be cheating in the NFL was the perfect closing jab with the #BigBalls #NoDeflatedBalls hashtags for the mic drop.
