He just needed a thicker back and better inner biceps peak (while raising) and win all Mr. O he entered 
biceps didn't matter, it's genetic shape, i have very peaking biceps, some of my friends have flat ones, he had full biceps
he did need a bigger back, and i feel as the years went on his legs fadded....

he had huge quads early on...not so much later on
kevin didn't really put everything together at one time
he got his back better by the end but the legs had faded
