I'm pretty sure enthusiasm has more effect than just def and reb. I agree that playing CTvsN is different than playing TIE-N. We can ofcourse argue about those team ratings and what they represent (for example having one 450k monster can boost your ID a lot while I still score a lot inside at every other position than C etc.). Remember that coachparrot is not written by a BB.
I'm not saying TIE at ent 7-8 = N at ent 5. Some just have stated it. It's a bit more complicated. Looking at point difference it creates might imply that it's the truth, but game outcomes have more variables in them than just ent (game shape, matchups, HCA, etc etc).
