While Ben Koyack was the lone Irish player drafted this year, a few other guys didn't have to wait too long to find out they'd get their shot too.
Shortly after the conclusion of the 2015 NFL Draft earlier today, Cody Riggs, DaVaris Daniels, and Kyle Brindza were all signed as undrafted free agents. Cam McDaniel, the other Irish player who has a shot at being an undrafted free agent this year, has not been signed to this point but has had workouts and interviews with a few teams, most notably the hometown Cowboys.
Cody Riggs was signed by the Tennessee Titans.
