I am fortunate that I don't listen to him.

As far as the OL theory, you could probably do that with any other position. Especially if you combined positions to make 5 players (like an OL). You can measure a team's success on # of starts their DBs and the strong side LB have. I bet the numbers would be similar.

And you're absolutely right about his examples. That is selective sampling at its finest. Pick 5 teams that did well. See if they fit your theory. Use them as an example.

I don't get the NFL theory. Just that good teams have good picks so they trade them, and bad teams don't?
