Anyone who thinks that is delusional - no arguments from me.
However there is a fine line between delusion and the other extreme which many are bringing around here.
Defense does win in the NBA. Toronto was 9th in opponents scoring. Something much bigger - much, much, much bigger - that I have brought up this year a few times is their opposition field goal percentage. Toronto was tied for 6th with Dallas and Indiana and they were just 0.1% behind Miami at 5th.

A lot of good was done this year and the team is in much better shape moving forward than many give credit for.
