Rich Eisen -- Smoked By Smokin' Cheerleader ... In 40 Yard Dash (VIDEO)

Here's a hot Atlanta Falcons cheerleader destroying NFL Network analyst Rich Eisen in the 40 Yard dash ... in glorious slow motion video.

With the NFL Combine in full swing -- some NFL teams are letting staffers take a shot at the 40 yard dash at their home training facilities ... like ATL Falcons cheerleader Katy.

While Eisen put up a pretty decent number at the main event in Indy (5.94) ... Katy tore that ass up (5.77)!!

By the way ... Roary the Lions mascot and Blitz the Seahawks mascot also hit the track ... and clocked in SLOWER than Katy.

Cheerleading ... it's a sport people.
