According to Adam Rittenberg of ESPN, the Colorado Buffaloes have reportedly parted ways with defensive coordinator Tyson Summers.
Sources: Tyson Summers is out as #Colorado's defensive coordinator. A surprise as Buffs defense excelled and improved in many areas, especially tackles for loss, red zone and third- and fourth-down D. Summers came to CU under Mel Tucker. Hearing Karl Dorrell wants his own guy.

Summers coached two seasons at Colorado, as he was brought in from the Georgia staff by former head coach Mel Tucker. His first season was solid for a first-time coordinator, particularly with the rash of injuries the 2019 Buffs suffered on the defensive side.
Tucker left for Michigan State only a year after he was hired. He brought some assistant coaches with him to East Lansing, but Summers remained in Boulder. His 2020 defense was very good, and even carried CU to a couple wins, although much of that credit should go to the upperclassmen who led the defense.
As Rittenberg noted in the above tweet, this departure is a sign head coach Karl Dorrell wants his own guy coaching alongside. Dorrell was a late signing for Colorado following Tucker’s departure. He had little time to build his staff, so it made more sense to keep the holdovers and only replace the empty coaching slots. Now that he’s had time to reassess and figure out who exactly he wants on staff.
Summers will not be the only change in the coaching staff. We don’t know who exactly will be on the way out, but all signs are pointing towards Darian Hagan staying on staff until the sun burns out.
