MIAMI -- Keep an eye on Reggie Williams. He could be the next player worth adding off the waiver wire.

Golden State has a way of turning unknown players into Fantasy stars thanks to coach Don Nelson. His open offense allows almost any player to fill up the stat sheet on a given night, and Williams could be the next sensation in your league.

The Warriors signed Williams to a 10-day contract Tuesday after he was called up from the Development League's Sioux Falls Skyforce. With Golden State dealing with prominent injuries to Monta Ellis (back), Corey Maggette (hamstring) and Andris Biedrins (hernia), there is plenty of opportunity for any player to step up and play well.

That's been the case all season for the Warriors, who also have dealt with season-ending injuries to Kelenna Azubuike (knee) and Raja Bell (wrist). Fantasy owners have jumped on adding players like Anthony Morrow, Anthony Tolliver and C.J. Watson.

Thanks to Nelson, those players have shined.

"Coach is awesome," said Tolliver, a former D-League player who has bounced around from San Antonio, New Orleans and Portland and stuck with the Warriors after a 10-day contract. "He's on a whole different level. He's just so laid back. He just lets us play and lets us do what we do.

"If it's your night, he's going to continue to feed you the ball. He's going to run plays to get you the ball and get you looks. He's not afraid to run plays for a guy like me. He just instills confidence in you by doing stuff like that. He plays you a lot of minutes and puts the ball in your hands."

We know what Ellis and Maggette can do when healthy, and rookie Stephen Curry has also become a Fantasy star this year. But Nelson has relied on undrafted players and former D-League standouts to play heavy minutes this season due to injuries.

Tolliver is one of those players. He has averaged 9.1 points and 5.7 rebounds in 24 games with the Warriors and has become a quality Fantasy reserve. He's even been a starting option in some leagues due to the recent injuries.

"I've had some stints with a few other teams in the league, but this has turned into that opportunity that everybody dreams of," said Tolliver, whose ownership on CBSSports.com has increased to 42 percent. "To come into a situation and play from Day 1 and get lots of opportunities to show what you have -- this has been an unbelievable blessing. I've been able to do pretty well."

Morrow also has seen a boost with the injuries, and he's living up to lofty expectations from prior to the season. In the NBA Summer League, Morrow scored 47 points for the Warriors against a team from the New Orleans Hornets. He set the record for the most points scored in a game at the NBA Summer League.

Morrow, who went undrafted out of Georgia Tech in 2008, got off to a sluggish start in the regular season and then suffered a knee injury in January. But he returned on a hot streak, averaging 18.5 points in February, and has been a solid Fantasy option ever since with his ownership up to 80 percent.

Nelson said Morrow's best asset is his shooting, and he's already made 100 three-pointers. For the season he's averaging 13.3 points and 3.9 rebounds.

"He possesses the one skill," Nelson said. "He's a guy that can shoot with range, better than anybody else in the league. He's trying to pick those other skills up like the mid-range jumper. He's working on his ball-handling and his passing. He's not there yet, but he's working hard at it."

Watson, another former D-League star who caught on with the Warriors in 2008 with a 10-day contract, has also been on a recent tear. He's scored in double figures in his past nine games with five 20-point outings over that span. He's also had at least two steals in all nine games and has done well filling in at point guard for Ellis with four games with at least five assists. Watson's ownership has increased to 67 percent in Fantasy Week 19 with Ellis out.

Ellis and Maggette could return for Fantasy Week 20, but both have battled injuries all year and could continue to miss time. Biedrins, however, won't return any time soon since he's expected to see a specialist Monday. That could allow Tolliver, Morrow and Watson to remain viable Fantasy options for the rest of the season.

"Everybody has got a chance," Curry said. "We had a lot of D-League call ups. Young guys are playing significant minutes. It's been an interesting year, but it's a great opportunity for them. They're doing well with the minutes they are getting."

And then there is Williams, who scored 10 points in his NBA debut against the Heat in 20 minutes off the bench. He also made two three-pointers, grabbed five rebounds and had five assists. He followed that up with 13 points, six rebounds and three assists against Orlando on Wednesday.

Not bad production for a player from the Sioux Falls Skyforce. But in Golden State, anyone can become a Fantasy star, and Williams might just be next.
