The Lakers have remained economical throughout free agency, choosing less grandiose moves designed to strengthen their foundation instead of chasing the kind of transactions that could compromise long-term investments or precious salary-cap space for next summer.After agreeing to a one-year, $18 million deal with free-agent guard Kentavious Caldwell-Pope late Tuesday night, the team is still considering several options for who could represent the final piece to their roster. The deal with Caldwell-Pope, 24, brings the Lakers up to the salary cap ceiling, and that leaves them with a $4.3 million salary-cap exception they can use to sign another player.The Lakers maintained interest in signing veteran free-agent guard Rajon Rondo after meeting with him on Tuesday, according to league sources familiar with the situation. Though they have not met with 22-year-old Tyler Ennis since free agency started, the player they acquired in a midseason trade with Houston remains a possibility to re-sign with them. Other free-agent guards who could fit the Lakers’ needs include Ian Clark, Isaiah Canaan and Ramon Sessions, though the Lakers have not been pursued them as aggressively.Meanwhile, the Lakers had to waive second-year guard David Nwaba on Wednesday, a move made to create enough salary-cap space to fulfill Caldwell-Pope’s deal, according to a league source familiar with the team’s thinking. The Lakers had exercised a $1.3 million team option on June 28 to retain Nwaba, but that contract was non-guaranteed and gave them extra cap space beyond their original $17 million to spend on a free agent.

Nwaba, who starred at University High of Los Angeles and Cal Poly San Luis Obispo before going undrafted, also averaged 6 points and 3.2 rebounds while shooting 58 percent in 19.9 minutes through 20 appearances with the Lakers last season.Once Nwaba clears waivers in the next 48 hours, any NBA team can sign him, while the Lakers can then sign Caldwell-Pope. It’s possible the Lakers could re-sign Nwaba to a less expensive deal if no other team claims him.
