The Cowboys are auditioning four players today, including former Giants quarterback Ryan Nassib, as Todd Archer of ESPN.com tweets. Safeties Jeron Johnson and Duke Williams and wide receiver Lance Lenoir are also working out for the team. 
To date, Nassib has spent his professional career as a clipboard holder for Eli Manning. Since being selected in the fourth round of the 2013 draft, the Syracuse product hasn’t made a single start for the Giants. Nassib received praise from Giants coaches for his work in practice, but the team didn’t make much of an effort to retain him this offseason.
Nassib’s workout will be key for the Cowboys since they only have have preseason games and the occasional regular season cameo on film to evaluate him on. If signed, Nassib could compete for the No. 3 QB role behind Dak Prescott and Kellen Moore. Recently, the Cowboys claimed Zac Dysert off waivers from the Cardinals and he is also hoping to make the cut.
Cowboys need to bring in as many backups as possible to audition.
They need defense…… They have no secondary
God I hate the Cowboys. With that being said I agree they need defense. Their offense is becoming stacked
Ironic no CKap mentioned
