No mention of Marino (score of 16). I guess he wasn't very successful.
Call it the Rule of 26-27-60.
Here is the gist of it: If an NFL prospect scores at least a 26 on the Wonderlic test, starts at least 27 games in his college career and completes at least 60 percent of his passes, there's a good chance he will succeed at the NFL level.
The most notable exceptions to the rule are Brett Favre, who scored a reported 22 on the Wonderlic, and Donovan McNabb, who scored a reported 14. http://sportsillustrated.cnn.com/2010/writers/john_lopez/07/08/qb.rule/index.html?xid=cnnbin&hpt=Sbin
