Brooklyn Nets head coach Steve Nash dismissed criticism of the team's roster moves, insisting "it's not like we did anything illegal".

The star-studded Nets have built an NBA super team, with Brooklyn now boasting former All-Stars Blake Griffin and LaMarcus Aldridge alongside James Harden, Kevin Durant and Kyrie Irving.

Griffin and Aldridge were both acquired after the pair reached contract buyouts with the Detroit Pistons and San Antonio Spurs respectively.

Amid criticism as the Nets eye their maiden championship, first-year coach Nash told reporters on Monday: "I don't hear it. I live in my Nets bubble.

"I don't know what anyone says about us, to be honest with you. … It's not like we did anything illegal. I don't know what we're supposed to do, not try to add to our roster and just sit pat?"

The Nets – who reached back-to-back NBA Finals in 2002 and 2003 – are second in the Eastern Conference, behind the Philadelphia 76ers this season.

Nash added: "That's the idea of this league is to try and put together the best team you can put together, and that doesn't guarantee you anything. … Nothing is set in stone.

"You got to try to put together the best team you can, and then you gotta build that team. ... We're hoping that we have all the pieces and that it's just a matter of how hard we work and how hard we care and the investment we put into this."
