Joe Flacco watched football from his couch last season before joining the Cleveland Browns in November, leading them to the playoffs and earning the AP Comeback Player of the Year award.
Several accomplished free agents are in a similar position waiting for a call this season.
Ryan Tannehill, who went 30-13 while leading Tennessee to the postseason from 2019-21, has remained unsigned since his contract with the Titans expired. The 36-year-old quarterback started eight games last season and said last month that he's staying in shape and will be ready if the right situation comes along.
Trevor Siemian, who was 2-1 in three starts for the New York Jets last season, also has been available for months.
Desmond Ridder began last season as Atlanta's starting quarterback. The 2022 third-round pick was released by Arizona on Tuesday after failing to beat out Clayton Tune for the backup job behind Kyler Murray.
Mike White, Bailey Zappe and Brett Rypien also are among the QBs who became available when rosters were trimmed to 53 players on Tuesday.
Here are five of the top remaining free agents:
XAVIEN HOWARD: A former-time Pro Bowl cornerback, Howard is another player who could help Dallas. The Cowboys lost All-Pro cornerback DaRon Bland for up to eight weeks and they let Stephon Gilmore walk away in free agency. Trevon Diggs is still working back from an ACL injury and the Cowboys are inexperienced at both outside cornerback spots. The 31-year-old Howard played his first eight seasons in Miami. He was limited the past two seasons by groin, hip and foot injuries.
