"I feel like I don't have anything left to prove in college football and my mom agrees," Briscoe said. "I want to be a consistent deep threat for an NFL team. I can get over corners and I'm a smart player."
Briscoe said he would have entered the NFL draft even if Jayhawks coach Mark Mangino had been retained. Mangino resigned Thursday evening after a tumultuous second half of the season that included an internal review of allegations of mental and emotional abuse of players.
Kansas lost its last seven games after a 5-0 start.
"Coach Mangino told me it was the right decision," Briscoe said. "As far as Coach, he was national coach of the year two years ago. I can't say he said the things they said to me. But that's all above me."
Briscoe finished the season with 84 receptions for 1,337 yards and nine touchdowns. He also is KU's career leader with 3,240 receiving yards.
"I'm very excited, and I feel like I'm blessed," Briscoe said to reporters during a news conference, "because I made it through three seasons injury-free. It's an honor to even be mentioned and know that I'm going to the NFL."
Briscoe will be a tempting pick for any NFL team. He has good hands and outstanding downfield speed, piling up 14 games with more than 100 yards receiving. Against Oklahoma in 2008, he set the school single-game record with 269 yards receiving.
He did have two key fumbles, however, in a 41-39 loss to Missouri in the regular-season finale that kept the Jayhawks from becoming bowl-eligible.
One red flag, however, will be a history of poor work habits. He was not allowed to join spring practice last year and was benched for the season opener for unspecified disciplinary reasons. He was known to have a tendency to be late for meetings and practice.
"Obviously, I had some problems during the offseason," Briscoe said. "Coach Mangino, I just want to thank him because he gave me the opportunity to stay around. The stuff I did, other head coaches would have just booted me off the team. I want to thank him for that. A lot of things have helped me mature."
