In theory, when a quarterback is getting No. 1 overall hype, teams want all the boxes to be checked. Alabama quarterback Bryce Young won't be able to check all the boxes. 

The 21-year-old is incredibly poised beyond his years. He throws with NFL-veteran-level anticipation and creates off structure as a runner and outside-the-pocket passer naturally as any quarterback prospect since Patrick Mahomes.

Young, too, will be unprecedentedly small for the position as a professional. Especially for a top-tier quarterback prospect. And that will undoubtedly scare teams considering the former Heisman winner within the first few selections of the 2023 NFL Draft. But does height and weight matter at the quarterback position in the NFL? With Young, the answer is complicated. 

Until Young is measured at the outset of his combine experience inside Lucas Oil Stadium next week, we won't know exactly how small he is. But being listed at 6-foot, 194 pounds isn't an encouraging indicator for Young. In most scenarios, players are listed a touch bigger than their actual size. Here are how some notably small, high-caliber quarterback prospects measured in at their respective combines over the past 25 years.
