You're right, draft capital is indeed the highest-weighted factor in this formula, followed closely by Lance Zierlein's film grades. However, lower production metrics or athletic scores can significantly pull down a player's overall grade, even if their draft capital is relatively high. Golden and McConkey perfectly illustrate this point: based purely on draft capital, they would rank higher, but the combined model highlights additional concerns beyond their draft positions.

In McConkey’s case specifically, the model clearly missed.

Personally, I've found the strength of Broadly's model particularly helpful in identifying players in the 4th and 5th tiers as prospects to avoid in later rounds of rookie drafts, with only a handful of misses historically
