Steelers' JuJu Smith-Schuster Pokes Fun at Isaac Newton Fact

On Thursday, Pittsburgh Steelers rookie wide receiver JuJu Smith-Schuster compared himself to none other than Sir Isaac Newton—sort of. 

This past June, a David Letterman parody account tweeted the following: "Sir Isaac Newton was only 23 when he discovered the law of gravity." 

Smith-Schuster evidently found the tweet months later, as he responded with his own statistic: "I was only 20 when I went 97 yards on Sunday Night Football." 

The first-year pro turned 21 years old last month, and he hit the Detroit Lions for a 97-yard score, seven catches and 193 receiving yards when the Steelers defeated Detroit 20-15 on Oct. 29. 

We'll let you decide which is the more impressive feat.
