Celtics guard Marcus Smart is extension-eligible this offseason, but president of basketball operations Brad Stevens – who has coached Smart for the last several seasons – has been frustrated by his “unpredictable play,” sources tell Chris Mannix of SI.com.

Two people familiar with the Celtics’ thinking tell Mannix that Smart appears more likely to be traded than extended before the start of the 2021/22 season. When Boston shopped Smart last season, the team sought multiple first-round picks, but one Eastern Conference executive who spoke to Mannix suggests the guard’s value is more along the lines of one first-rounder and possibly a rotational player.

Here’s more from Mannix:

• Although re-signing Lonzo Ball doesn’t seem to be the Pelicans‘ top priority in free agency, several rival executives expect New Orleans to match any offer Ball receives if the club strikes out on its top free agent point guard targets, writes Mannix. That would allow the Pels to avoid losing Ball for nothing and would create the option of trading him down the road.
• The Trail Blazers haven’t given any indications at this point that they intend to deal Damian Lillard or CJ McCollum, according to Mannix, who says forward Nicolas Batum is among the free agents on Portland’s radar.
• The Sixers‘ asking price for Ben Simmons remains high. “Forget a Harden haul,” one exec in contact with the 76ers said to Mannix. “They want what Boston got for KG and Pierce.”
• Mannix adds the Mavericks to the list of teams that are expected to show interest in point guard Dennis Schröder.
• Teams are “increasingly wary” of Victor Oladipo‘s long-term health and multiple executives believe the two-time All-Star may go unsigned for a few months while he gets healthy following his latest quad tendon surgery, says Mannix.
• Mannix believes the Thunder could be in the mix for Zach Collins, observing that the big man is the kind of low-risk/high-reward player that Sam Presti loves.
