Former Washington standout Jake Locker reportedly scored 20 on the Wonderlic test at the recent NFL Scouting Combine, the lowest tally among this year's crop of quarterbacks.
Joining Locker on the low end was Auburn's Cam Newton, who reportedly had a 21. Former Arkansas standout Ryan Mallett is said to have scored 26.
On the other end of the scale were Greg McElroy, formerly of Alabama, and Blaine Gabbert, formerly of Missouri. McElroy is said to have scored 43 and Gabbert 42.
Other reported scores: Colin Kaepernick (Nevada) 37, Christian Ponder (Florida State) 35, Ricky Stanzi (Iowa) 30 and Andy Dalton (Texas Christian) 29.
The Wonderlic is used to assess the aptitude of prospects. A perfect score is 50, and only one of 100,000 people ace the test. Pat McInally of Harvard is believed to be the only player to score 50.
