Top pick Chung the latest in Patriots’ fold

Chung reported to the team in Foxborough yesterday, which was the Patriots’ rookie reporting date for training camp. (The veteran reporting date is Wednesday, with the first full-squad practices Thursday.)

Chung’s reporting to camp means that he and the Patriots have been able to agree to contract terms.

In response to an e-mail query, Patriots spokesman Stacey James confirmed that all rookies under contract reported yesterday.

As a second-round pick, the longest deal Chung could agree to is a four-year pact, per the league’s collective bargaining agreement. The Patriots’ other three second-round picks, nose tackle Ron Brace, cornerback Darius Butler, and offensive tackle Sebastian Vollmer, all inked four-year deals.

The 5-foot-11-inch, 212-pound Chung was the first of the Patriots’ second-rounders, taken with the second pick in the round (No. 34 overall). That was the pick the Patriots obtained from the Chiefs in exchange for quarterback Matt Cassel and outside linebacker Mike Vrabel.

A two-time first-team All-Pac-10 selection at the University of Oregon, Chung finished his career with 384 tackles, 9 interceptions, 19 tackles for loss, 26 passes defended, and 4 sacks. He started 51 consecutive games for the Ducks, tying teammate Max Unger for the school record.

Playing the rover position last season, Chung recorded 92 tackles, 6 1/2 for loss, and 2 sacks. He returned his only interception of the season 31 yards for a score against Arizona.

By being on time, Chung is actually a little bit early, based on the experiences of the Patriots’ previous two top picks.

In 2007, Brandon Meriweather missed the first day of practices while his contract was ironed out. Last year, linebacker Jerod Mayo sat out the morning session on the opening day of camp while his deal was finalized, but he participated in the afternoon session.

Both Meriweather and Mayo were first-round picks, an important distinction when it comes to negotiations. The Patriots traded out of the first round this year, making Chung their highest overall selection.

Chung is the 10th of the Patriots’ league-high-tying 12 draft picks to reach a deal, leaving just long snapper Jake Ingram, a sixth-round pick, and linebacker Tyrone McKenzie, a third-round pick, as those who have not been reported to have settled on deals.

A call to Ingram’s agent, Wynn Silberman, was not returned yesterday. However, a report on WEEI.com last week said talks had hit a snag over the structure of Ingram’s bonus, with the Patriots wanting to make part of the signing bonus payable as a 2010 roster bonus.

There is no great rush with McKenzie because he is out for the season after tearing the anterior cruciate ligament in his right knee during rookie minicamp in May.

Like all draft picks participating in a minicamp without a contract, McKenzie received an injury protection agreement from the Patriots.

Before draft picks participate in a minicamp, their agents receive a tender letter and an injury protection agreement from teams. The injury protection agreement specifies that in the event of a career- or season-ending injury, the team will negotiate in good faith based on the contract the player at that spot signed the year before.

McKenzie was taken with the 97th overall selection. Last year’s 97th overall pick, Bengals receiver Andre Caldwell, received a reported four-year, $2.265 million contract with a $560,000 signing bonus.
