Here's what I was originally responding to:
"There aren't many NFL guys who even want to cut, outside of smallish RBs facing a blitzing LB. It's known as 'dirty football' for good reason and I suspect was probably used against our OL recruiting during PJ's tenure. At the end of the day, these guys are all co-workers (with a few exceptions) and aren't interested in diving at knees unless absolutely necessary (again, see RB picking up blitz)"
I responded:
"The San Francisco 49ers, Houston Oilers, Denver Broncos, and Atlanta Falcons all say hello. See:
https://en.wikipedia.org/wiki/Cut_blocking
Needless to say, the colleges have been using this technique for eons."
What you were saying is that "NFL guys" don't want to cut block. I pointed out that not only do they cut block but that multiple NFL teams have made cut blocking their usual blocking method. That doesn't have anything to do with "dirty football" or whether the NFL uses the spread option. Again, these were attempts to get away from your original argument.
On another note, you are mistaking civility for "being polite", a common error. You were mistaken. I could have hemmed and hawed around that, treating you with kid gloves. But think a minute what that actually says: that you aren't worth a straightforward argument because you can't stand being contradicted. I don't think that at all; you seem like a person who likes to argue, sure, but you don't seem completely unreasonable. I treated you accordingly. That, my friend, is being civil.
