Halliday endured plenty of ups and downs with the Cougars but showed enough ability to earn a shot in the NFL. Playing in Mike Leach's Air Raid offense, the signal-caller set numerous school records and threw for an NCAA single-game record 734 yards in 2014, but suffered a season-ending broken leg on Nov. 1. He attended the NFL Scouting Combine in February but didn't work out as he continued to recover from the injury. He did take part in a pro-day workout for scouts in April.
