While NFL players are mostly known for what they do on game day, there are some who also shine in their academic endeavors. These are the players who actually respected the term "student-athlete" for what it is.
For a top-level football player at a school with a top-level football program in today's NCAA, "athlete-student" is the apt description.
But there are some who valued the former rendition of the term. Rarely are football and academia mentioned in the same sentence, but for these 10 players, the two may carry equal importance.
Here are the top 10 smartest players in the NFL.

Smith was the president of his high school senior class, graduating one semester early with an impressive 4.4 GPA.
