CHICAGO -- Connor Cook set Michigan State records for passing touchdowns and yards through the air while becoming the winningest quarterback in school history.

It didn't mean very much in the NFL draft.

Cook was selected by Oakland with the second pick of the fourth round Saturday, with the Raiders making a trade with Cleveland to jump ahead of Dallas out of fear the Cowboys might be looking for a potential successor to Tony Romo.

"I'm glad I found a home," Cook said. "A little bit of a wait. I'm glad the whole process is over."

Oakland already has Derek Carr, who threw for 32 touchdowns last season, but the 6-foot-4 Cook represented good value at No. 100 on the draft's third day. He passed for 9,194 yards and 71 touchdowns with the Spartans, but questions about his leadership skills pushed him down the board.

Six quarterbacks were drafted before Cook was picked by the Raiders.

"Anytime you see another quarterback drafted in front of you it hurts," Cook said. "I'm a competitor. Obviously I think I'm one of the best quarterbacks in this draft class. But things are never easy. Nothing is ever perfect."

Baylor nose tackle Andrew Billings, another one of the top names on the board coming into the day, was drafted by Cincinnati at No. 122. He was a first-team AP All-American in his last season with the Bears, leading the team with 15 tackles for loss.

The Browns selected Wisconsin linebacker Joe Schobert with the first pick of the fourth round. The 6-1 Schobert had 9 1/2 sacks for the Badgers last season.

The impressive draft showing for Ohio State continued when San Diego grabbed linebacker Joshua Perry with the 102nd pick, and Jacksonville continued its defensive focus when it selected Notre Dame tackle Sheldon Day at No. 103.

Perry made 105 tackles and three sacks during his senior year with the Buckeyes, who had 10 players selected in the first three rounds, a record for the modern era of the draft since 1967.

Day had four sacks and two forced fumbles for the Irish this season. Jacksonville also selected three defensive players in the first three rounds, including Florida State cornerback Jalen Ramsey at No. 5 overall, and UCLA linebacker Myles Jack in the second round.
