Steroids are more effective than today's supplements ( like deer antlers) at adding muscle mass, and they were not outlawed. Steroids also had a side benefit, roid rage.
I met Joe Greene in the National Record Mart at 5th and Liberty back in 1976, and thought he was the biggest person I'd ever seen, @ 6'4" & 270lbs.... Some of the guys today, are closing in on a 100lbs more and 4 inches taller. I don't think better food and training would have added another 50-70lbs and 4 inches to Greene's frame for him to play in today's game., certainly not at DT.
One other point, I'm not so sure that with these players playing at the weight they do, is conducive to maintaining proper joint and muscle health. They have built themselves up to the point where they are violating the laws of physics exceeding their engineering capacity, which is why we see all of these muscle pulls, tears and ligament issues.
you make a fantastic point - I actually think due to the emergence of the passing game, we are going to see speedier, athletic, leaner guys on the defensive side of the ball - def a transition at what we're looking for on the D-line. Being taller with long arms is being sought over bulk and power. Now - that said, the taller guys are taller, and the faster guys are faster, and the hits are at higher speeds IMO - so yea, while we will see different body types now than in the past 10-20 seasons, there will be more damage just because of evolution, also - because the league is mandating less "football-ready" conditioning - aka if you aren't practicing taking a pounding as much before the season starts, you are seeing teams not being conditioned for it until later in the season.
