ALLEN PARK -- Tyrell Crosby has become the first of what is sure to be a wave of draft picks signing their rookie deals with the Detroit Lions this week.

Rookie minicamp is this weekend, and the Lions are in the good habit of locking in almost their entire class before it opens. Last year, eight of their nine draft picks had put pen to paper before they touched a practice field in Allen Park.

Kenny Golladay, a third-round pick, was the lone holdout. He eventually signed on June 19, a couple days into the summer break.

This year, Crosby's deal was the first to be announced. The Lions think they got really good value in him, too. They had him among the five best players headed into Day 3, and were shocked he was still available to them in the fifth round.

"He was well ahead of everybody else on the board at that time," general manager Bob Quinn said. "We had him graded a lot higher than where we probably took him. So, thought the value was just too good to pass up. Size, toughness, playing strength, played left tackle in college, has practiced at other spots. We see him as a guy that has multiple positions along our front."

Crosby played both right and left tackle at Oregon, didn't allow a sack last year and was named the Pac 12's offensive lineman of the year. He's expected to compete for a reserve tackle role behind Taylor Decker and Rick Wagner. Corey Robinson and Brian Mihalik are the other top contenders for those jobs.
