The Nets are 4-2 on the season and won their second straight game Sunday, but Johnson said they "haven't played anybody."
"I just didn't think as individuals, as players, that we all have each other's back out there," he said. "Offensively guys kind of exhaust their options and then when there’s nothing else for them they’re passing. When they have to."
As a team, the Nets are averaging 20.2 assists per game this season, which is 18th in the NBA.
Brooklyn is about to embark on a three-game road trip, and Johnson said his team will lose if it continues to play the way it has. The trip features games against the Phoenix Suns, Golden State Warriors and Portland Trail Blazers.
"There’s no way you can play like we’ve played," he said. "You can’t go out on the road like that...Those will be double-digit losses."
The Nets have won four-of-five and this is the most frustrated I've seen Joe Johnson as a Net. Only time it was close was early last season.— Andy Vasquez (@andy_vasquez) November 11, 2014
Damn, Joe Johnson erupts on Nets after practice. Calls team "selfish." Must be bad, mild mannered Johnson an unlikely candidate to blow up.— Chris Mannix (@ChrisMannixYS) November 11, 2014
Through six games this season, Johnson is averaging 19.8 points, 5.8 rebounds and 3.8 assists.
The Nets (4-2) play the Suns (4-3) on Wednesday.
