Grizzlies second round pick Josh Selby is averaging 21 points on 50-percent shooting, 5.7 rebounds, 2.3 assists and a steal in three games with the D-League Reno Bighorns.

Lionel Hollins said Selby's D-League stint would give him "an opportunity to see four or five game tapes to see exactly what he is."

Selby averaged 10.3 minutes in 18 games with the Grizzlies this season.

"We've been trying to patch him in at point guard,” Hollins said. “Is he a point guard? We don't know. Is he better at the off-guard spot? We don't know. He's never played it for us. I'd just like to get an opportunity to see him when he's playing a lot of minutes."

Zach Randolph has been cleared to begin non-contact basketball drills, which puts him on pace to return in early March.

Randolph underwent a third MRI test on his right knee Monday morning, with the results showing more healing as Randolph recovers from a torn right medial collateral ligament.

The Memphis Grizzlies have assigned Josh Selby to the Reno Bighorns, the Grizzlies’ NBA Development League affiliate.

This is the first assignment for Selby of his career. 

Selby (6-2, 183, Kansas) has appeared in 18 games for the Grizzlies this season, averaging 2.9 points and 1.4 assists on 39 percent shooting in 10.3 minutes.   

The NBA announced the reserves for the 2012 All-Star Game on Thursday.

Joining LeBron James, Dwight Howard, Derrick Rose, Dwyane Wade and Carmelo Anthony on the Eastern Conference team are Chris Bosh, Luol Deng, Roy Hibbert, Andre Iguodala, Paul Pierce, Joe Johnson and Deron Williams.

Kobe Bryant, Chris Paul, Blake Griffin, Andrew Bynum and Kevin Durant will have LaMarcus Aldridge, Marc Gasol, Kevin Love, Steve Nash, Dirk Nowitzki, Tony Parker and Russell Westbrook on their Western Conference team.

The Grizzlies waived Josh Davis following Monday's game.

Davis would have earned $854,000 if he remained with the team until the end of the season.

Memphis could bring Davis back later on a 10-day contract.

Tony Allen can act as a defensive wrecking ball on his best nights, causing an opponent’s top option to crumble.

"My whole thing is getting guys focused," Allen said. "I play with a lot of passion. I play with a lot of heart and soul. I play like this is my last. I play like I may not ever get back on the court again. I'm going to tire myself out. I'm going to be yelling. I'm going to be screaming. But I always hope that has a snowball effect."

Allen was voted the NBA’s best perimeter defender in the annual general manager survey.

"He's like an Army general," Mike Conley said. "He says crazy things but goes out there and backs it up. He works as hard as he speaks. ... He gives 100 percent on every possession."

The Grizzlies lead the league in opponent turnover percentage at 17 percent, with Allen forcing 13.4 percent of the team’s takeaways.

"Defensively, he talks to everybody," Rudy Gay said. "He's always helping everybody on the court when it comes to defense."
