I think that a lot of what you are saying is only true if you don't understand American football all that well. Blocking schemes are far more complex than just "smash whoever is in front". WR's run much more complex routes than just a single route as well (option routes depending upon the coverage and coverage technique). His analogy is limited (as all analogies are, at some level), but it works for its intended purpose, IMO.
