The college football season is in full force and with a full slate of games on Saturday, we at PFF and our team of over 500 analysts has dissected and graded every player on every snap of every game to bring you the most detailed and valid set of picks you can find anywhere.

The Week 4 Eckrich Big 12 Team of the Week powered by PFF saw some impressive performances and, of course, the strength of opponent also factored into the overall selections as did the PFF player grades.

Purdy finished the game against UL-Monroe with elite-level overall and passing grades as he threw for 435 through the air with three touchdowns and added three more rushing touchdowns on the ground.

Second-Team QB: Sam Ehlinger, Texas

Running Back

Darius Anderson, TCU

Anderson totaled 168 yards on the ground, gaining a whopping 145 yards after contact. He averaged 8.0 yards per carry but had to earn 6.9 yards after first contact with the defender in a big outing despite the result.
