NFL executives and coaches are preparing Thursday for Missouri's pro day, which will represent the first and possibly only offseason throwing workout for quarterback Blaine Gabbert, the potential No. 1 overall pick in next month's draft.

We've noted a few times that the Minnesota Vikings are in the market to draft a quarterback. To that end, I wanted to pass along some interesting information posted Thursday morning by ESPN's Chris Mortensen.

Gabbert scored a 42 (out of a possible 50) on the written Wonderlic test during last month's scouting combine. The average for all players is traditionally around 20.

To be clear, there is plenty of debate about how accurately the Wonderlic can assess someone's mental aptitude for football -- the daughter of the test's founder recently said the NFL mis-uses the information -- but there is no doubt it factors into a team's assessment.

Here are some of the scores recorded by other prominent quarterback prospects, according to Mortensen:

I'm not going to draw any conclusions about these players' football intelligence, or lack thereof, based on Wonderlic scores. I encourage you to keep an open mind as well. But unless and until the NFL stops giving the Wonderlic test, we have to assume the scores will play some role in ranking and grading prospects.
