My question is this: Why were his players consistently rated higher than mine, even though, in most cases,
mine did just as well or better stat-wise?
Aside from offensive contribution (which is typically easy to see), player rating also contains defensive contribution. That's not necessarily steals and blocks -- it's more along the lines of how good were the shots taken against each particular player.
