Feliciano could turn into starter on line

Oakland offensive line coach Mike Tice came into the dining room Saturday afternoon, happy not only to break his diet with a slice of pizza but also to contemplate having drafted a big, tough piece of clay to mold.

The Raiders selected Miami’s Jon Feliciano in the fourth round to get their third day of the NFL draft off to a belated start. The Raiders had traded down twice, adding three later picks, before taking the 6foot-5, 316-pound guard at No. 128.

Feliciano is a tatted-up mountain of a man who should be able to compete for the Raiders’ starting right-guard position.

“I fit what Raiders’ players are supposed to be like,” Feliciano said in a conference call.

Big, tough and light on their feet, Tice said.

“Our guys are going to have to be able to run,” Tice said. “They’re going to have to be able to pull. Jon pulls well already so that’s good. I’m excited to add him to the mix. It’s going to be good for our room.”

Big-money free-agent signee Austin Howard started at right guard last year for the Raiders, but is being moved to right tackle. And it’s no guarantee he starts there either, Tice said.

“The whole right side is wide open,” Tice said, referring to the guard and tackle spots.

Howard is competing with 2013 second-round pick Menelik Watson at right tackle. Feliciano could push returning players Khalif Barnes and Matt McCants at guard. Feliciano can play tackle as well, Tice said.

The Raiders also added some linebacker depth with fifthrounders Ben Heeney from Kansas and Neiron Ball from Florida. Oakland then took a development pass-rusher in 20-year-old defensive end Max Valles in the sixth round, and tackle Anthony Morris, kick returner Andre Debose and cornerback Dexter McDonald in the seventh round.

Oakland obviously thought it had a find in Feliciano, as it traded down twice in the fourth round and still got him. Carolina gave up fifth- and seventhround picks to move up from 124th overall to 102nd, and then Tampa Bay sent Oakland a seventh-rounder to jump from the 128th position to 124.

“We saw some depth on the board and took advantage of the opportunity,” head coach Jack Del Rio said.

Heeney is a good run defend- er but did have 16 missed tackles last season, according to Pro Football Focus. That was the most for any draft-eligible inside or middle linebacker from a Power 5 conference.

Ball, meanwhile, is lucky to be playing football, much less getting drafted. He missed the entire 2011 season when he had bleeding in his brain and required surgery. He missed the last three games last season because of knee surgery.

Ball was one of five players drafted from a Florida school, along with second-round pick Mario Edwards Jr., third-round pick Clive Walford, Feliciano and Debose. Some of that has to do with the firsthand experience of new defensive line coach Jethro Franklin (who was at Miami) and linebackers coach Sal Sunseri (Florida State).

“That was part of it,” Del Rio said. “We were obviously tied in … but Sal Sunseri wasn’t running the draft board.”

When all was said and done, Del Rio said the Raiders added some productive college players as well as some other players they think can be better at the next level than they have showed recently.

“We like the guys ... we got,” and the draft “was a good, solid effort,” Del Rio said. “We’re just trying to put one day after another in making this a better football team.”
