Worst player on each NFL team 2015

#26. Dallas Cowboys: Matt Cassel

PFF grade (position rank): -11.7 (34th)
2015 salary cap hit: $1.8 million

Considering Tony Romo’s lengthy medical history, Dallas probably should have invested more in a decent backup quarterback heading into 2015. Instead, they rode with Brandon Weeden as the No. 2 guy in training camp. Things predictably unraveled after Romo fractured his collarbone in Week 2.

Weeden was summarily dumped after a few ineffective starts for Cassel, who turned out to be a shell of the player who once capably replaced Tom Brady for an entire season.

Cassel tossed five touchdowns and seven interceptions in eight starts, averaging just 6.3 yards per attempt, the second-worst mark in the league. He practically disintegrated into dust in December until he was mercifully replaced by long-time third-stringer Kellen Moore during an especially brutal shellacking by the Jets.
