Willis completed three of six passes for 50 yards, one touchdown and one interception in Saturday's 20-7 preseason win over the Seahawks.
Willis started in the absence of Jordan Love (thumb) and played with the majority of Green Bay's top skill-position players. His longest completion went for 39 yards to Matthew Golden, and he later capped the same drive with a one-yard touchdown toss to Romeo Doubs. Willis also displayed some inconsistency as a passer, as he overthrew Malik Heath for an interception to end the Packers' first drive. Willis will enter the season as the backup to Love.
