Jordan Bell’s physical tools have long been unquestioned. At 6-foot-9 and 224 pounds, with a 7-foot wingspan, a 37-inch vertical leap, lateral quickness and a knack for timing blocks, Bell has all the makings of a prototypical small-ball center.

But two seasons into his NBA career, Bell remains somewhat of an enigma. Too often, he makes a dazzling sequence, only to follow it up with a puzzling one. Bell’s averages last season of 3.3 points, 2.7 rebounds and 1.1 assists in 11.6 minutes per game were down in each category from his rookie year.

His work ethic and maturity are also concerns. At times, Bell has needed reminders from Golden State’s elder statesmen that optional workouts aren’t optional for him. In a late January win over the Lakers, with the outcome long not in doubt, Bell got into a heated argument with head coach Steve Kerr during the team huddle.

Little more than two months later, Bell was suspended for a game against Memphis for charging a gift shop candle to assistant coach Mike Brown’s hotel bill without permission. The Warriors had reason to believe that wasn’t the first time Bell had done this to Brown.

With the deadline to give Bell a qualifying offer looming, Golden State must decide whether he figures into its long-term plans. His potential is obvious. But when given numerous opportunities to crack the front-court rotation last season, Bell underwhelmed.

In December, after center Damian Jones sustained a pectoral injury in Detroit, Bell started to log regular minutes out of necessity. Bad habits resurfaced. Instead of letting plays develop, he often got impatient, reaching for steals or biting on pump-fakes.

There were also times when Bell was reluctant to take the open shot. After laboring in a few brief appearances during the first round of the playoffs against the Clippers, he fell out of the rotation, only to be forced into a meaningful run with the front-court depth depleted in Game 6 of the Western Conference semifinals.

In 11 minutes he was a two-way force, posting four points, two rebounds, two blocks and an assist. Kerr was impressed enough to play Bell 13.5 minutes per game in the Warriors’ sweep of Portland in the Western Conference finals. In the NBA Finals, Bell appeared in three games.

For the first time in his NBA career, Bell won’t participate in Summer League, putting the onus on him to develop on his own. The question is whether the Warriors will keep him around to see whether he can overcome his inconsistency.

Offseason outlook: The Warriors have until Saturday to tender Bell a $1.8 million qualifying offer, making him a restricted free agent. With only one center (Jones) under contract for next season, Golden State probably feels Bell is worth the investment.

But if another team tries to lure him away by offering more than $1.8 million, don’t expect the Warriors to get into a bidding war. Eric Paschall, who was drafted last week with the No. 41 overall pick, is a similar player to Bell who might be more ready for a rotation role.
