I believe Dye liked to get a a par 5, a par 3, and a par 4 in the final trio of holes, in whatever order they worked out. I'm not familiar with him building many par 3 18th holes, so yeah, he has a lot of par 3s at 17, but other times it would work out to be the 16th (La Quinta Mountain, La Quinta Dunes, Honors Course, ASU Karsten, Citrus Club, Carmel Valley Ranch, French Lick, Promontory, and many others).
