Tim “Wunderkind” Tebow put his brain on display for the NFL talent investigators via the NFL version of the IQ test, the Wonderlic Test. It wasn’t pretty. Tebow scored a 22 out of 50. The test is timed and does require that one have some intelligence. It is intended to see how a player thinks under pressure. What remains unclear is how seriously it is used by teams to determine the draft value of a player. However, as the article in the link above points out, Tebow won awards for his achievements off the field as well.
Tebow graduated Florida with a 3.66 GPA as a Family, Youth and Community Services major, and he is a three-time member of the SEC Academic Honor Roll and a two-time First Team Academic All-American.
Draw whatever conclusions you like but keep in mind that Matt Leinart scored a 35 on the damn test.
