Came across some interesting info (at least interesting enough for the off-season). In 2013, the quarterbacks with the top Wonderlic scores were:
1.Blaine Gabbert 42
2. Alex Smith 40
3. Eli Manning 39
4. Matt Flynn 38
5. Colin Kaepernick 37
For those who are unfamiliar with the Wonderlic test, it is used by the NFL to gauge intelligence. 50 is the maximum score, NFL players overall average about 20.
The reason this is interesting is that 3 of these 5 (Gabbert, Smith, Kaepernick) played for the 49ers under Harbaugh. (Also of note: Andrew Luck was ranked 7th, also with 37). Although it is already known that Harbaugh looks for smart football players, this info illustrates how heavily player intelligence factors into his decisionmaking, and perhaps provides some insight into recent recruiting offers.
