I know that 5-6 games are not the season. Many things could change, but let's have a look to the eastern conference standings.

I think that Atlanta-Boston-Orlando and Miami are out of reach.
Is it realistic point to the 5th position ?
Chi-Ind-Cle-Nj and Mil are not better than knicks.

Atlanta 6 0 1.000
Boston 5 1 0.833
Orlando 3 1 0.750
Miami 4 2 0.667
New York 3 2 0.600
Chicago 2 3 0.400
Indiana 2 3 0.400
Cleveland 2 3 0.400
New Jersey 2 3 0.400
Milwaukee 2 4 0.333
Washington 1 3 0.250
Toronto 1 4 0.200
Charlotte 1 4 0.200
Detroit 1 5 0.167
Philadelphia 1 5 0.167
