King,
I love this newest addition to your list of things to change about the NFL that is never going to happen. Limited substitution would lead to a very interesting game, but I don't see it ever happening with the NFL - there is no way to get there from here. My guess that is one of the things that people like about Arena football, though personally I am only reminded that the Arena Football League still exists once or twice a year, so I can't really say.
Also, I have a possible correction. Near the bottom of the first page its says, "But the age of specialization has led to players who do nothing other than block on the offensive line, or clog up space in the trenches as an offensive tackle." Did you mean to say offensive or defensive tackle at the end? I guess that it makes sense either way, but defensive tackle seems like a better fit since defensive tackles tend to be gigantic as well.
