Dual Olympian Mark Worthington has more reasons than most to avoid the relaunched NBL but is giving it another go, despite the financial woes that beset three of his four previous teams.

Forward Worthington recently signed a three-year deal with Melbourne Tigers after returning from Serbian club Radnicki Kragujevac.

He knows better than most that a multi-year contract is no guarantee of security.

Worthington was forced to look elsewhere after two of his former NBL clubs, 2007 champions South Dragons and Gold Coast Blaze folded, while a third, Sydney Kings, dropped out of the league for a period after he left them.

With his friend Chris Anstey coaching the Tigers and Worthington having a house in Melbourne he said it was logical to sign with the club, who he played for in the 2009-10 NBL season.

Worthington, who has also plied his trade with clubs in Germany and Puerto Rico, decided to return to the NBL, despite the problems he encountered in the past.

"It was disheartening, I wouldn't lie about it, the way that my career has panned out with the different (NBL) clubs," Worthington told AAP.

"But having said that you just can't beat Australia and after seeing as much as what I've seen, I've no regrets coming back.

"I obviously did my homework before signing with Melbourne and it seemed to be a very established club and (I'm) very happy to be with them.

"I'm pretty confident the club is heading in the right direction and (with) the rebranding of the NBL itself."

Worthington, 30, has recently resumed playing after undergoing a shoulder reconstruction and participated in last weekend's pre-season Blitz tournament in Sydney.

A veteran of the Boomers program with two world championship campaigns to add to his 2008 and 2012 Olympic appearances, Worthington is keen to extend his international career under new coach Andrej Lemanis.

"Just doing my usual role with the Boomers and hopefully be the energy guy that I've been for the last decade," Worthington said.

"It's been a fun role, something that I've really cherished and hopefully I get to stick in that role for another three more years.

"Hopefully we'll get a third world champs this coming off-season and hopefully a third Olympics as well."
