Kendricks started every game for the Golden Bears over the last three years. He had 105 tackles and 2.5 sacks last season when he was the Pac-12 defensive player of the year.
Philadelphia already upgraded its linebackers by acquiring two-time Pro Bowl pick DeMeco Ryans in a trade with Houston. The position was a revolving door last season, especially the first month when the Eagles tried three different linebacker combinations in the first four games.
Ryans should solidify the middle and Kendricks will compete for a starting spot on the strong side.
Kendricks is the fourth linebacker the Eagles have selected in the second round in Reid's 14 seasons as head coach. Barry Gardner (1999), Quinton Caver (2001) and Matt McCoy (2005) were the others. Only Gardner developed into a starter.
"You are getting a phenomenal pass rusher off that side and pass-coverage skills are a strong part of his game," Reid said. "He's a stout kid and he plays a physical game. He's a tenacious player."
The 6-foot-5, 243-pound Foles could compete with Mike Kafka and veteran Trent Edwards for the backup job behind Michael Vick. Foles is a strong-armed, pocket passer who threw for 4,334 yards as a senior.
Foles played at Michigan State as a freshman before transferring to Arizona. He finished his career with 10,068 yards passing, 67 touchdowns and 33 interceptions. He attended Westlake High in Austin, Texas, where he broke several of Drew Brees' passing records.
"You're getting a big man, but also a big athlete, not necessarily a runner but he has good feet and good presence," Reid said. "I like the way he throws the football and he's also a smart guy, which helps."
Coming off a disappointing 8-8 season that began with Super Bowl aspirations, the Eagles addressed defense with their first three picks. They traded up to take Mississippi State defensive tackle Fletcher Cox at No. 12 overall on Thursday night.
The defense ranked eighth last season in total yards allowed, though those numbers may be deceptive. Defensive coordinator Juan Castillo had a tough time adjusting to his new role after spending most of his career coaching the offensive line. A slew of high-priced, talented players had chemistry issues in the first half and struggled adapting to a new system and, in some cases, playing different positions.
They seemed to come together during a four-game winning streak that ended the season, and hope that their new additions will help them carry that momentum into this season.
"It wasn't a plan to go with defense," Reid said. "We went with the best player available. It's welcomed. We were playing very good defense at the end of the year and this increases competition."
