The Mac Jones hype train might need a little maintenance.
The 23-year-old quarterback was riding high entering the New England Patriots' bye week, boasting a 70.3% completion rate (third in the NFL) and looking like the clear favorite to win Offensive Rookie of the Year.
But Jones appears to have hit a rookie wall: He completed just 43.8% of his passes for 145 yards with zero touchdowns and two interceptions in Sunday's disappointing loss to the Buffalo Bills, which followed an underwhelming effort in New England's Week 15 defeat against the Indianapolis Colts.
