The switch was made because veteran quarterback Joe Flacco has struggled badly.Flacco has thrown for two touchdowns and six interceptions in four games, including zero TDs and three picks in his last two outings. The Browns started the season 1-3, and the offense looked flat.Meanwhile, Gabriel showed promise in limited snaps and earned his shot. In limited game action, Gabriel went 3-for-4 with 19 yards and a touchdown. Moreover, Flacco suffered a minor injury during the Browns’ blowout loss to the Lions (34-10), which opened the door for Gabriel to step in. Previously, Gabriel beat out Shedeur Sanders and Kenny Pickett for the backup role.Amid Gabriel's promotion to QB1, Shedeur responded to the Browns’ decision to keep him as QB3 with silence on Tuesday. He mimed his answers with a smile.Backing Deion "Coach Prime" Sanders' son, former New England Patriots wide receiver Rob Gronkowski said Shedeur Sanders should be promoted to QB2 for the Browns, replacing Joe Flacco, after Gabriel was named the starter. He believes Flacco is no longer the right fit and that Sanders deserves a real shot.Dillon Gabriel’s fiancée Zo Caswell dedicates her outfit to Browns QB before Week 3 clash vs. PackersAhead of his Week 3 game against the Packers on Sept. 21, Zo Caswell wore a brown halter-neck top with Dillon Gabriel’s No. 8 stitched on it.
