Sports fans love to compare athletes from different disciplines and imagine how they'd do in games that aren't their own.
And this week's episode of CBS's Game On! took that fantasy to the next level, pitting Venus Williams against the Tampa Bay Buccaneers' Rob Gronkowski in a series of challenges involving sprinting, football, tennis and basketball.
In the sprinting event, competitors had to blast through a paper barrier at the fastest speed possible. Venus had a strong showing of 14.0 mph, but Gronk just barely beat her number, running 14.2.
