Then the most serious test period of Anderson's life begins.
The 6-foot-10 sophomore forward will participate in portions of the NBA predraft camp at Orlando, Fla., beginning May 27, before working out for 10 NBA teams during a two-week tour of the country.
On June 14, Anderson will be back home in El Dorado Hills to begin final deliberations with his family to decide by the June 16 deadline whether to keep his name in the draft or return to Cal for his junior season.
"I'm amazed how calm he is about this," his mother, Sue Anderson, said. "I can't believe it. He's really working hard, but he sleeps through the night."
"I'm kind of just trying to live life normally right now," Anderson, 20, said. "I've just got to think of it as a blessing. It all needs to be fun. It's actually exciting, if anything. It's awesome to hear the feedback I'm getting from (NBA) teams.
"Once that (decision) day comes, I'm sure I'll be feeling butterflies."
Anderson said he is no closer to making a decision than he was six weeks ago when he declared himself one of 69 underclassmen eligible for the draft.
"It's really just a matter if I'm comfortable with what they're saying," he explained. "If they tell me there's a guaranteed (draft) spot, and I'm comfortable with that, then I'm going to look hard at that."
Of course, there are no true guarantees until draft day on June 26.
"That's the scary thing about it," he conceded.
Anderson will undergo a physical including being weighed and measured at Orlando, and will complete drills that test strength, quickness, speed and agility. But he has decided against playing in the camp, opting instead to show his on-court skills during individual workouts with teams.
Anderson said his tour itinerary is not yet complete, but that he expects to visit primarily teams drafting in the 15 to 25 range of the first round. That could exclude both the Sacramento Kings and Golden State Warriors, slotted for the Nos.12 and 14 spots, respectively.
"We have an idea of the teams that are really serious about picking me," he said.
For Anderson, who averaged a Pac-10-leading 21.1 points along with 9.9 rebounds this past season, life has been hectic since the Golden Bears' season ended March 24.
Cal fired coach Ben Braun, replacing him with former Stanford and Warriors coach Mike Montgomery.
"He's an awesome guy. I'm excited to play for him," Anderson said. "He's given me feedback and advice. Of course, he might be a little biased."
For a period of a month after the season, Anderson worked out three or four times each day, completing Montgomery's offseason assignments, and spending time with his own Sacramento-based trainer, Guss Armstead.
Armstead, who has worked with NBA players including Andre Miller, Matt Barnes and Kevin Martin, has helped Anderson with ballhandling and developing a better midrange shot off the dribble.
"I think he'll surprise people in those (workout) settings because his skill set is so high," Armstead said. "I think he's the most underrated player in the country. But the process will help Ryan. It's a win-win for him."
Anderson's immediate challenge is getting a grip on the game's most basic implement.
"The NBA ball is unbelievably slippery," Anderson said, laughing. "My shot isn't quite there right now. It's really that ball that's messing me up."
