Nafua Whyte won the Roosters' Jack Gibson Medal as the club's player of the year after the grand final, while Tedesco drew the night's plaudits.
Mark Nawaqanitawase received the clubman of the year award before his move to rugby union.
The Roosters have confirmed at least eight departures ahead of next season.
Spencer Leniu was the latest to announce his exit, with Parramatta confirming the front-rower's signing on Thursday.
He joins Connor Watson, Daly Cherry-Evans, Nawaqanitawase, Angus Crichton, Daniel Tupou, Fetalaiga Pauga and Jake Elliott among those leaving.
Nawaqanitawase and Crichton are heading to rugby union, while Cherry-Evans is moving to Super League and is likely to finish his career there.
Elliott, who did not make his Roosters debut, is reportedly set to sign with the North Queensland Cowboys.
He would compete for a debut and provide cover, while learning alongside halves player Tom Dearden; Jake Clifford and Liam Sutton are also available.
The Cowboys introduced several young players in 2026, but coach Todd Payten will be expected to improve on the team's inconsistent performances.
Long-term fullback Scott Drinkwater is joining the Dragons next season, with Jaxon Purdue set to take the Cowboys' No. 1 jersey.
The Roosters will retain most of their squad, and Whyte is expected to continue his strong form. Rueben Garrick will join from Manly next year.
