[10] The Raiders had received the 79th pick used to select Koonce in a trade that sent Rodney Hudson to the Arizona Cardinals.

[13] Koonce made his NFL debut on December 5 and, despite taking the field for only seven plays on defense and four on special teams, recorded a sack of Washington quarterback Taylor Heinicke.

By Week 14 against Minnesota Vikings, Koonce had roughly doubled his playing time under interim head coach Antonio Pierce.

[16] Koonce had his best statistical game as a pro in a Christmas Day matchup against their division rival Kansas City Chiefs.

Koonce harassed Chiefs quarterback Patrick Mahomes all game, finishing with career highs in pressures (8) and sacks (3).
