Weeden passed for a Browns rookie-record 3,385 yards, but only completed 57.4 percent of his throws and tossed 17 interceptions to 14 touchdowns.
"I'm not going to comment at all on what happened last year," said Chudzinski, who replaced Pat Shurmur after Cleveland's 5-11 campaign. "I will tell you what I see when I look at Brandon. He has some tools, a good arm, and the ability to get the ball down the field. I'm looking forward to working with him."
Weeden took all of the snaps with the first-team offense during the two-hour practice, while Campbell worked with Cleveland's second unit. The session was held inside the Browns' field house.
Chudzinski cautioned not to read too much into their assignments, stressing "we're early in the process."
"Jason will get some reps with the ones along the way, as well," he said. "There's not a lot to see yet on the field because we've only put in a portion of the offense. But I have been impressed with all three quarterbacks with the way they've picked up things and have been able to verbalize them in meetings."
Campbell, who said he would speak to reporters Thursday, has 14,682 career passing yards and has completed 60.9 percent of his throws. At 6-foot-5 and 230 pounds, Campbell also stands two inches taller and is 10 pounds heavier than his competition.
"I'm glad to have Jason on board because he's a veteran guy who can help the Browns," Weeden said. "But I'm also glad he's here because he's a good dude. We met last year in the preseason when we played Chicago, and I really liked the guy."
NOTES: All NFL teams that make coaching changes are given one bonus minicamp in the spring, which the Browns chose to hold at their team training facility. ... RB Trent Richardson declined comment on a civil lawsuit in which he was named last month. According to the document filed in Cuyahoga County, two plaintiffs claim they were verbally and physically abused at Richardson's home on Dec. 9, 2012. "I can't say nothing about that," he said. "I wish I could, but I can't." ... Starting LG Jason Pinkston has been medically cleared to resume physical activities, but Chudzinski said he will be brought back slowly. The third-year pro fell ill during Cleveland's game against Cincinnati on Oct. 14 and was diagnosed with a season-ending blood clot. ... Three NFL veterans — WR Legedu Naanee, WE Seyi Ajirotutu, and DB Chris Rucker — are participating in minicamp on a tryout basis. ... WR David Nelson should be ready for the start of training camp, according to Chudzinski. Nelson tore his right anterior cruciate ligament in Buffalo's 2012 season opener, requiring reconstructive surgery, and signed with the Browns on April 8.
