That's a pretty uncharitable way to frame HRB's post. I took him to mean that the Mavericks were playing better (getting results) because they were playing better, i.e. were executing better at both ends. For specific reasons he could probably elaborate on, but weren't necessary to address my open statement. He didn't use the word "peaked" once - you put that in his mouth, sarcastically, twice.
Glancing at Dallas's pre/post ASB splits, they are winning at a much higher rate (32-23 vs 18-9), driven by higher steals, blocks, fewer fouls, and consequently much improved defense (117.2 p/g pre, 112.4 post). CTG has their defense rated #6 since Feb 1st on a rating basis. So there's something going on there, which isn't just results-oriented faux-analysis.
