Much of the pre-draft coverage on Florida QB prospect Anthony Richardson has centered around his incredibly high ceiling and pegged him as a boom-or-bust pick. Sky's the limit, but, there are red flags.

The logic seems pretty sound. He blew up the combine with a QB record 40.5-inch vertical and 10-foot, 9-inch broad jump, while running a 4.43 40-yard dash with a body (6-foot-4, 244 pounds) that more closely resembles Derrick Henry. He can break a long run at any time or launch the ball 75 yards through the air. 

On the flip side, his overall lack of experience and accuracy issues are concerns. His 13 career starts in college would match Mitchell Trubisky for the fewest by a QB drafted in the first round since 2000. His 24 career touchdown passes would be the fewest by a first-round QB since Michael Vick (drafted first overall in 2001). The last first-round QB with a college completion rate as low as Richardson's (54.7) was Jake Locker (54.0 -- eighth overall pick in 2011).

NFL Draft predictions: How many QBs in the top 4? Will the receivers slide?

But what if Richardson actually has the highest floor AND ceiling of any QB prospect in this year's draft? The recent history of high-drafted QB prospects who were elite rushers suggest that Richardson actually may have a higher floor than you think.

In case his rushing prowess is in question, he ran for 654 yards in 12 starts last season (54.5 rushing yards per game) while leading all FBS quarterbacks with 6.3 yards per rush. He showed off his ability at Florida with plays like this.

He's without a doubt an elite rusher. So I looked at the 66 QBs drafted in the first round since 2000, splitting them into three categories. Elite rushers, the middle and statues. I chose 18 elite rushers based on ranking the QBs in terms of most rushing yards per game in a season in their college careers, with Lamar Jackson at the top (123.2 rushing yards per game) and Josh Allen at the bottom of the elite rusher list (37.4 rushing yards per game). 

Here's the full list. Lamar Jackson. Johnny Manziel, Cam Newton, Vince Young, Jake Locker, Deshaun Watson, Kyler Murray, Robert Griffin III, Tim Tebow, Trey Lance, Michael Vick, Marcus Mariota, Alex Smith, Justin Fields, Carson Wentz, Daniel Jones, Trevor Lawrence and Josh Allen. It's not perfect (Carson Wentz at North Dakota State is the one big outlier) but mostly captures QBs with a rushing profile like Richardson, with a big enough sample size to draw some conclusions.
