Rams DL Aaron Donald has announced his retirement after 10 NFL seasons. He won three defensive player of the year awards, 2014 defensive rookie of the year, and eight first-team All-Pro honors. The coming season will be the Rams' first without Donald in the lineup since 2013. From 2014-2023, he missed just nine total regular-season games. L.A. will obviously be hard-pressed to ever find another D-lineman near Donald's level. Expect them to look for help in that area with the 19th pick in the upcoming NFL Draft, though.
