Fourth-rounder Thornton, meanwhile, has seen the opposite dynamic with 113 snaps and 14 targets over four games. Raiders' rookie WRs Jack Bech and Dont'e Thornton have a long way to goSeparation issues and a lack of rapport with quarterback Geno Smith have left Thornton's box scores quieter than the opportunity suggests. Rookie ball-carrier Ashton Jeanty has been a focal point of the offense, and Las Vegas hasn't wasted any time getting him involved. When the quarterback isn't in rhythm, coaches tend to lean back on veterans and tight ends over younger receivers still earning equity. The production gap between opportunity and output isn’t permanent, but right now, it's defining their underwhelming rookie storylines.
