Schroeder still owns the Redskins single season record with 4109 yards passing.
But he didn't really do much after leaving DC.
His best season as a Raider was in 1990 when he passed for
2849 yards, 19 TDs and 9 INTs.
Other than that he was pretty mediocre. The Skins definitely got the better end of the deal with Lachey.
