I think we can safely say that Dukes will have chronic hamstring problems.
I'll bet anything that Dukes does plenty of squats/leg presses and doesn't work the hamstrings as hard (with lots of heavy hamstring curl sets). You can do stretching all day long, but hammy-pulls will still occur when the quads get over-developed in relation to the hamstring, and you can tell how built-up Dukes' quads are.
