NAPA — Raiders training camp came to a close after 18 practice sessions Thursday. Some training camp awards and observations as with the team returning to its facility in Alameda:

Most outstanding player: RB Darren McFadden. With defenders not allowed to hit him low, and unable to unload on him high, he’s impossible to deal with on a practice basis. Has looked terrific during two preseason games as well.

Most outstanding newcomer: LB Philip Wheeler has the speed and athleticism to cover downfield, the burst to rush the passer and is stout at filling in gaps against the run. New defensive system is made for him.

Most outstanding rookie: WR Rod Streater, undrafted out of Temple, has been a standout in camp and has 13 catches in two preseason games — only six fewer than he had all last season in college.

Most improved: DE Lamarr Houston dropped some weight and has been difficult to contend with both outside and when he moves inside to tackle.

Best leader: QB Carson Palmer. Palmer spends nearly every moment when he’s not under center in the ear of his offensive teammates, talking strategy and keeping the line of communications open.

Best nickname: FB Owen Schmitt is the ‘Runaway Beer Truck.’

Biggest hit: Mike Goodson had his mouthpiece knocked out on a hit from Wheeler and was taken to the hospital by ambulance. Fortunately, he was OK.

Most troubling injuries: WRs Denarius Moore and Jacoby Ford. Moore’s hamstring in the first week of camp robbed him of time with Palmer in the new offense. Ford’s foot injury halted a strong camp as well as his ascension to being the return specialist for both kickoffs and punts.

Area of least concern: Place kicking, punting. With Shane Lechler back after a knee injury, the snap, spot, kick issues through two preseason games should evaporate.
