BERKELEY -- Allen Crabbe's father said Monday that the Cal basketball star is unlikely to make any decision about his future until just before the April 28 deadline for underclassmen to enter the NBA draft.

"Probably not going to happen," Allen Crabbe Jr., said. "It's really a disadvantage with the way they set it up now."

Crabbe, the Pac-12 Player of the Year, will receive an evaluation from the NBA Undergraduate Advisory Committee on or before April 15. But rules implemented by the NCAA in May 2011 make it impossible for players to work out for professional teams before actually entering the draft.

Players who declare for the draft now face an April 16 NCAA deadline with withdraw their name or lose their ability to return to college. That greatly limits their options.

"Unfortunately, there's no such thing as testing the waters anymore," Cal coach Mike Montgomery said. "Most of the teams aren't going to make their ultimate decision until they get the chance to work you out. And you have to put your name in the draft to be able to have a chance for that."

A 6-foot-6 shooting guard who averaged 18.4 points and 6.1 rebounds this season, Crabbe is considered a possible first-round pick in the NBA draft. Cal's season ended Saturday with a 66-60 loss to Syracuse in a third-round NCAA tournament game at San Jose.

Crabbe's parents plan to meet with their son Wednesday to begin the dialogue about his future, Allen Crabbe Jr. said.

"I didn't even bother him with this at all. He had enough to deal with during the season," Crabbe's father said. "We're going to sit down and evaluate both scenarios, and consider his options for next year."

The process is made more difficult by rules that went into effect before the 2012 draft, which essentially prevent underclassmen from getting a complete evaluation on their prospects from NBA teams.

If a player declares for the draft and receives new information or sustains an injury after the April 16 "withdrawal" deadline, he has no recourse.

As a result, few players will opt to make their decision until just before the April 28 NBA deadline.

"That's probably the safest and surest route to go at this point," Allen Crabbe Jr. said. "We don't have much ammunition to work with."

The new NCAA rules been criticized as apparently self-serving, and Montgomery agreed they don't provide the best opportunity for players to get a thorough evaluation from NBA teams.

"You're going on word-of-mouth," he said. "We'll get all the information we can and provide that to his family and as a result of that make the best decision and go from there."

Montgomery said Cal already has filed the paperwork to the NBA for evaluations on both Crabbe and junior guard Justin Cobbs.

The NBA advisory committee consists of general managers, assistant GMs and player personnel executives who have extensively scouted college games. The evaluations they provide offer no guarantees of how high a player might be drafted and tend to be conservative.
