Former Redskins Mike Shanahan was fired by owner Dan Snyder at the end of last season.
Hall said that Griffin looks looser in camp and that it's "good to have two coaches that believe in you," referencing new head coach Jay Gruden and new offensive coordinator Sean McVay.

Griffin and Shanahan clashed last season over Griffin's health, the nature of the offense and other matters as the Redskins went from a playoff appearance in Griffin's rookie season in 2012 to a 3-13 record last year.
Gruden was previously offensive coordinator for the Cincinnati Bengals.
Last season -- Griffin's second in the league and his first after undergoing knee surgery -- he threw for 3,203 yards, 16 touchdowns and 12 interceptions. He rushed for 489 yards and no touchdowns, down from 815 yards and seven touchdowns in 2012.
