Nick Harper is a career quality starter — a defensive back whose body of work places Harper in the top quarter of all players at the position historically. The Knox model values sustained contribution over flash, and Harper's career arc reflects exactly that kind of reliable professional-grade performance.
A high-end defensive back defined as much by excellent availability over their career as by their on-field impact (top 20% all-time). Coaches and teammates could count on them being available.
Worth 109 points of value above a freely-available replacement cornerback — top 22% of all 4,649 ranked at the position. 8 of 9 seasons cleared the replacement bar, by +13.6 on average.See board →
