Sam Hartman takes responsibility for his performance in the preseason opener.

Washington Commanders reserve quarterback Sam Hartman got an opportunity on Friday to potentially cement himself as the clear-cut third-string quarterback. Instead, the former Notre Dame signal caller might have played himself off the Commanders roster altogether. The second-year pro completed less than half of his passes -- 9 of 19 -- for 64 yards and an interception.

It's the same thing for Khalid Kareem. Kareem is in his second year with Atlanta and recorded two tackles, a sack against Detroit. Both Okwara and Kareem are competing for a roster spot, and both are trending upward after playing well on Friday.
