The matter was part of the issues discussed by management when it held its first meeting with Vanguardia and returning team manager Johnson Martinez on Tuesday.
Blackwater owner Dioceldo Sy and team governor Siliman Sy met with Vanguardia and Martinez at the company office in Kalookan City.
Veteran big man Kelly Nabong is among those who has an expiring contract with the franchise, but could likely be re-signed owing to his good showing with the team despite going winless in 11 games in the PBA Philippine Cup.
Vanguardia, 48, is set to conduct exit interviews with Nabong and the rest of the players as his initial move in taking over the coaching job from Nash Racela.
He will also see who among the current coaching staff are going to stay, but will definitely be bringing long-time partner Tino Pinta along with him.
"We spoke about the lineup, the coaching staff, and next year's possible rookie draft," said Vanguardia.
The new Blackwater coach said members of the coaching staff will be announced by management on Friday.
