The Knicks will NOT SUCK next year ... well, at least they won't be as terrible ... so says Carmelo Anthony's wife.

We spoke with La La Anthony on the way out of FOX Studios in NYC Monday -- who told us Melo is still "100% dedicated to the team" ... and predicted a serious turnaround when they get back on the court.

Of course, it's hard to get any worse ... the Knicks finished the season this year with the 2nd worst record in the NBA -- only winning 17 games.

As for who La La wants the Knicks to select in the draft -- "I'll take anybody at this point."
