After catching a touchdown in front of his hometown during the first preseason game, undrafted free agent receiver Keelan Doss continues to impress the coaching staff.

In the second week of the preseason, Doss put another excellent game on tape, catching all five of his targets for 38 yards. According to Pro Football Focus, Doss was the team’s highest-graded offensive player (86.2) during Oakland’s second preseason game. Take a look at the top-five grades this week, courtesy of PFF:

Doss has pretty clearly outplayed Marcel Ateman, a fan favorite from the 2018 draft. If this trend continues, Doss will make the final roster, likely as the No. 5 or No. 6 receiver. The story of the undrafted rookie free agent UC Davis just keeps getting better and better.
