How much would Nagurski have weighed today?

Bronko Nagurski was a powerhouse football player of the 1920s and 1930s. He was 6-2 and weighed 226 pounds. Fans today would tend to downgrade him because he was not nearly as big as today's players. The question, however, is what Nagurski would have weighed had he played today with modern nutrition and training techniques.
